Vedclass · Answer

(C) The $pH$ value is inversely proportional to the concentration of hydrogen ions $[H^+]$.As the $pH$ value decreases,the concentration of $[H^+]$ ions increases,which means the acidity of the solution increases.Given $pH$ values are: $A = 1.9, B = 2.5, C = 2.1, D = 3.0$.Comparing these values: $1.9 Since lower $pH$ indicates higher acidity,the order of acidity is $A > C > B > D$.This is equivalent to $D < B < C < A$.

If the $pH$ of the aqueous solutions $A, B, C$ and $D$ are $1.9, 2.5, 2.1$ and $3.0$ respectively,then what will be the order of acidity?
