Acids are able to donate, split off, ionise into proton(s) and an anion.
Example:
Acetic acid --> proton and acetate
CH3COOH --> H+ + CH3COO-
It increases.
H plus ion concentration can be decreased by adding base to the solution. The reduction can also be done by accepting hydrogen ions.
Increase the concentration of SO2
Isotonic
That you have an acidic solution.
In an aqueous solution, the concentration of H3O+ is the same as the concentration of H+. If you know the pH of the solution, then that's equal to 10^(-pH).
10
acidic
It determines how acidic it is.
If the PH of lemon juice at 298 k is found to be 2.32, the concentration of H3O plus ions in the solution would be 0.5 M.
It will increase the pH
