Lemons (and lemon juice) are relatively low on the pH scale, compared to water, which is a neutral 7.
However, compared to other acids, it's not very strong, there are substances much lower on the pH scale.
believe it or not the acid in lemon is actually high. if you eat a lemon alone of course you can take the enamel off of your teeth. so if it can take the enamel off your teeth it is high in acid. hoped this helped! :)
Lemon juice can inhibit some bacteria if they are sensitive to lower (acidic) pH. As lemon juice is an acid. But there are very high numbers of bacteria in lemon wedges when tested. See link below:
Lemon juice!
Citric acid in the lemon. Sugars in the lemon juice as it dehydrates.
Lemon juice is an electrolyte. Electrolytes conduct electricity when in a solution of water
Lemon juice is an acid. The metal in the paper clip reacts with the acid to produce an electric current. It's the same process as the electricity produced in a battery.
An Acid. Such as battery acid, hydrochloric acid, Tomato Juice, acid rain, lemon juice, vinegar etc.
Citric acid, found in most fruits, has roughly a pH of 2 - which is quite low.
Lemon has Citric acid in it.
Pomegranite juice has a relatively high citric acid level.
Lemon itself is not an acid, but it contains acids.
Lemon juice has a very high acid content that causes a lightening of hair color.
A fruit with very high concentrated acid such as a lemon.
low burn your hair with high
The pH is low or the litmus paper turns pink.
it depends on how much acid is in a fruit. If there is a lot of acid the pH is low, and the fruit is sour. If the pH is high, the fruit is more likely to be sweeter, and there is little acid in the fruit. The acid that causes the sourness in the fruit can vary, but is in many cases citric or ascorbic acid.
Lemon juice is about 5% citric acid, a weak acid.
Tapioca is low in purines and as a result produces low uric acid.
