Foods such as Orange Juice and lemon juice are acidic in their natural state but turn alkaline after they have been metabolized in the body. As such, for dietetic purposes they are usually considered to be alkaline forming foods despite being acidic prior to consumption. Most fruits are alkaline except a few that include cranberries, plums and Prunes. These fruits are classified as acidic because they contain acids the body can't metabolize.
Lemon juice is acidic, because it has a concentration of hydrogen ions which give it a measured pH of about 2, and anything with a pH of less than 7.0 is acidic. Lemon juice is not technically itself an acid, however, because it's a mixture of compounds, including citric acid, ascorbic acid (vitamin C), and Pantothenic Acid (vitamin B5).
pH is a logarithmic measurment scale meaning 'power of hydrogen', and the values indicated by measurement are the negative log of the hydrogen ion concentration in a water-based solution. Since the measurement scale is logarithmic, that means that if a measured value changes by 1, the strength of acidity changes by 10; so, lemon juice at a pH of 2 is 10 times more acidic than apple juice at a pH of 3, and battery acid at a pH of 1 is 10 time more acidic than lemon juice. A pH of 7.0 is neutral, and anything with a pH over 7.0 is a base.
Lemon juice is an acid. As it contains an organic acid called citric acid it shows acidic characters and has a pH ranging between 2-3.
well both because fizzy water is neutral and lemon is acidic but i would say more acidic
Lemon juice contains citric acid and is mildly acidic.
it is acidic by its citric acid content.
Lemon juice is acidic.
depending on the amount you add, i think it will be neutral as lemon juice is an acid and baking soda is a base.
It is an acidic mixture; lemon juice contains citric acid, which is a almost a strong, three-fold acid.
Lemon juice has a pH of 2. So, it is acidic.
Lemon juice is acidic.
acid
Lemon juice contains an acid (but by itself it is not an acid, because it is not a pure compound): citric acid makes lemon juice acidic.
Ph3 is acidic. Equivalent to lemon juice. Ph0 is super acidic and 7 is neutral.
acid
An acid, Citric acid to be precise.
it a base
it is an indicator.
The pH of apple juice is 3. It is an acid.
