Vedclass · Answer

(C) The $pH$ of a solution is determined by the concentration of $H^+$ ions. Adding a solution with the same $pH$ (i.e.,same concentration of $H^+$ ions) will not change the $pH$ of the original solution.For $20 \ mL$ of $0.1 \ N \ HCl$,the concentration of $H^+$ is $0.1 \ M$,which corresponds to $pH = -\log(0.1) = 1$.Option $(c)$ provides $500 \ mL$ of $HCl$ with $pH = 1$. Since the concentration of $H^+$ ions in this solution is the same as the original solution $(0.1 \ M)$,adding it will not change the $pH$ of the original $20 \ mL$ of $0.1 \ N \ HCl$ solution.

On adding which of the following,the $pH$ of $20 \ mL$ of $0.1 \ N \ HCl$ will not alter?
