|
Ammonia with pH 13
|
|
|
Water with pH 7
|
|
|
Milk with pH 5
|
|
|
Lemon juice with pH 2

Explanation:
Detailed explanation-1: -Among the following, lemon juice is the most acidic substance. Thus, it has highest amount of hydrogen ions.
Detailed explanation-2: -However, H2SO4 being the strongest acid will dissociate completely thus giving the highest concentration of H+ ions.
Detailed explanation-3: -Lemon juice, with a pH of 2, has 10-2 moles (or 0.01 moles) of H+ ions in every liter of water. That is, there are more H+ ions in the lemon juice than in the water, so the lemon juice is more acidic.
