Although lemons are acidic, drinking lemon juice really does not have an impact on the pH of your body. Drinking lemon juice increases the acidity of urine, as the kidneys rid the body of excess acid. The pH of the blood is maintained between 7.35 and 7.45, regardless of how much lemon juice you drink.
Outside the body, lemon juice is acidic (pH is below 7). This is a non-issue. Everyone knows this. It’s a citrus fruit. Inside the body however, when lemon juice has been fully metabolized and its minerals are dissociated in the bloodstream, its effect is alkalizing and therefore raises the pH of the body (pH above 7 is alkaline).
Answer: Lemons are extremely acidic. Any chemical with a pH less than 7 is considered acidic. Lemon juice has a pH around 2.0, ranging between 2 to 3. To put that in perspective, the pH of battery acid (sulfuric acid) is 1.0, while the pH of an apple is about 3.0. Vinegar (weak acetic acid) has a pH comparable to lemon juice,
Martin Poole/Digital Vision/Getty Images Both lemon juice and vinegar contain acids—the former has citric acid and the latter has acetic acid. Both are relatively weak, but citric acid is slightly stronger. However, the strength of an acid is much more complicated than most people understand.
The pH of soda is about 2.5. Lemon juice contains two acids. The juice is about 5-8% citric acid, which accounts for the tart flavor. Lemons also contain ascorbic acid, also known as vitamin C .
No it does not. Lemon juice is less acidic than the gastric acid — primarily Hydrochloric acid — already present in the body. Gastric acid has a pH of between 1-2. Lemon juice has a pH of 2-3.
Why is lemon juice acidic?
Because they contain a high amount of citric acid, lemons have an acidic pH. Lemon juice has a pH falling between 2 and 3, which makes it 10,000–100,000 times more acidic than water. A food’s pH is a measure of its acidity. The pH of lemon juice falls between 2 and 3, meaning it is acidic.
Neutral foods: Natural fats, starches and sugars. Alkalizing foods: Fruits, nuts, legumes and vegetables. Proponents believe that eating high amounts of acidifying foods can cause your body’s pH to become more acidic, increasing your vulnerability to illness and disease.
Nevertheless, the Alkaline Diet categorizes foods into one of three groups: Acidifying foods: Meat, poultry, fish, dairy, eggs and alcohol. Neutral foods: Natural fats, starches and sugars.
Put simply, pH is a value that rates how acidic or alkaline a solution is on a scale from 0–14. A pH of 7 is considered neutral. Any pH value below 7 is considered acidic and any pH value over 7 is considered alkaline. On the pH scale, the difference between adjacent numbers represents a tenfold difference in acidity.
On the pH scale, the difference between adjacent numbers represents a tenfold difference in acidity. For instance, a pH of 5 is 10 times more acidic than a pH of 6 and 100 times more acidic than a pH of 7. Because they contain a high amount of citric acid, lemons have an acidic pH. Lemon juice has a pH falling between 2 and 3, …
Trusted Source. ). Normally, the kidneys keep the blood’s pH constant by getting rid of excess acid or alkali through the urine. Acidic nutrients such as protein, phosphorus and sulfur increase the amount of acid the kidneys must filter out.
What they fail to realize is that, while lemon juice may make the pH of the urine more alkaline, it does not have the same effect on the pH of your blood. In fact, several studies show that the foods you eat have a very limited effect on blood pH ( 5. Trusted Source. , 6. Trusted Source.
How to tell if lemon juice has high acidity?
One way to demonstrate the low pH—and therefore high acidity—of lemon juice is with a litmus strip or indicator solution. These change color when they come in contact with acids. Lemon juice dropped into an indicator solution or onto a litmus strip causes it to turn bright red, indicating its high acid content.
Strength of an Acid. The strength of an acid is a measure of its tendency to donate a hydrogen ion to a solution. The level of equilibrium—the point at which the acid stops giving up hydrogen ions—determines the strength of the acid. The lower the level of acid in a solution when this happens, the stronger the acid is.
When most people talk about acidity, they’re talking about pH. While pKa measures the strength of an acid itself, pH measures the amount of acid in a solution. As a result, the pH of vinegar and lemon juice doesn’t correspond directly to the strength of the acetic and citric acid in them because the amount of acid in the solution varies. For example, two different types of vinegar both contain acetic acid, but they may contain different amounts. Although the acid in both will have the same strength, the two types of vinegar may differ in their pH. As with pKa, the lower the pH of a solution, the more acidic it is.
The exact level of citric acid in lemon juice can fluctuate; but in general, lemon juice is highly acidic, with a pH of 2, because of the high percentage of acid it contains. In some cases, lemon juice can have a slightly higher pH of up to 2.6.
Both lemon juice and vinegar contain acids—the former has citric acid and the latter has acetic acid. Both are relatively weak, but citric acid is slightly stronger. However, the strength of an acid is much more complicated than most people understand.
For example, two different types of vinegar both contain acetic acid, but they may contain different amounts. Although the acid in both will have the same strength, the two types of vinegar may differ in their pH. As with pKa, the lower the pH of a solution, the more acidic it is.
Acetic acid is much weaker than citric acid, with a pKa of 4.74. The pH of vinegar can vary greatly depending on the specific type or composition. Some vinegar can be nearly as acidic as lemon juice, with a pH of around 2.4, while other types are much more basic, with a pH of over 3.
How many acids are in lemon juice?
The Acids in Lemon Juice. Lemon juice contains two acids. The juice is about 5-8% citric acid, which accounts for the tart flavor. Lemons also contain ascorbic acid, also known as vitamin C .
Any chemical with a pH less than 7 is considered acidic. Lemon juice has a pH of around 2.0, ranging between 2 and 3. To put that in perspective, the pH of battery acid (sulfuric acid) is 1.0, while the pH of an apple is about 3.0. Vinegar (a weak acetic acid) has a pH comparable to lemon juice, around 2.2.

in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels. Lemons are extremely acidic. Any chemical with a pH less than 7 is considered acidic.
While some people believe lemon juice has an alkalizing effect on the digestive system because of its mineral content, there is no scientific data to support this claim. The acid in lemon juice will attack tooth enamel. Eating lemons and drinking lemon juice can put you at risk for tooth decay.
Does drinking lemon water damage enamel?
The answer to this lies in whether a person sucks on fresh lemons or limes all the time. If so, then yes, doing so will damage the teeth’s enamel. But drinking lemon-water does not expose the teeth for excessive amounts of time to high citrus acidic levels in the mouth, thereby causing no harm to the enamel.
Simply put, outside the body lemon juice is acidic; inside the body after its minerals dissociate, its effect is alkalizing. So in fact, lemon juice is both acidic and alkalizing.
It’s a citrus fruit. Inside the body however, when lemon juice has been fully metabolized and its minerals are dissociated in the bloodstream, its effect is alkalizing and therefore raises the pH of the body (pH above 7 is alkaline). Please notice the difference.
Let’s get this straight and expound on 10 benefits of regularly taking lemon juice with warm water (note: NOT equal to lemonade!) Outside the body, lemon juice is acidic (pH is below 7). This is a non-issue. Everyone knows this. It’s a citrus fruit.
You may have heard that the acidity of lemon juice reduces the healthy enamel on teeth.
In these cases, lemon juice will cause an irritating “burning” sensation, because it has not yet been metabolized by the body and is still in its acidic state when passing these areas of the gastrointestinal tract. Therefore, other remedies would be suggested.
