Question

What effect does the concentration of H+ (aq) ions have on the nature of the solution

NCERT Class 10th Science Chapter 2 Acids Bases and Salts

Answer 1

H+ ion in aqueous solution is dissociated i.e released mainly by acids and this also represents the value of pH by
if concendration H+ ion is less than ($10^{-7}$) acidic
($10^{-7}$) or os neutral
if more than ($10^{-7}$) it is basic in nature 

Answer 2

higher the concentration of h+ ions  in a solution ,more acidic is the solution.....................
