I think they are both citric acid but lemon juice is more concentrated.
Lemon has a higher concentration of Citric acid that is why it is more sour.
Vinegar is more acidic than grapefruit juice. Vinegar typically has a pH of around 2.4 to 3.4 due to its acetic acid content, while grapefruit juice has a pH of about 3.0 to 3.8, primarily from citric acid. Therefore, vinegar is generally considered to be more acidic than grapefruit juice.
lemon has more acid.
a lemon is more sour than a grapefruit because it is more acidic.
Acid rain is more acidic than lemon juice. Lemon juice has a pH of around 2, while acid rain typically has a pH in the range of 4.2 to 4.4 due to the presence of sulfuric and nitric acids.
2.5 PH (vary from 2.3 to 4.0) Fresh tends to be more acidic than bottled.
Lemon juice is more acidic. Lemon juice has a pH of 2, which is very acidic. Sodium hydroxide is alkaline, with a pH of 14. However, I'd consider sodium hydroxide considerably more dangerous, as even a small splash can cause painful burning.
10 * 10 * 5= 500 times more acidic.===============
im pretty sure that it is lemon juice because it is the most sour
No, adding lemon juice to water does not make it alkaline. Lemon juice is acidic in nature, so it actually lowers the pH of water, making it more acidic.
no
Yes it is. The pH of water is neutral or 7, and lemon juice is a very low 1 or 2. With the water, the resulting pH is more neutral and less acidic than lemon juice alone.
