Vedclass · Answer

(D) The $pH$ scale measures the acidity or alkalinity of a solution.For acids,as the concentration of $H^+$ ions increases,the $pH$ value decreases. Therefore,a lower $pH$ indicates a stronger acid,and a higher $pH$ indicates a weaker acid. Thus,statement $(ii)$ is correct.For bases,as the concentration of $OH^-$ ions increases,the $pH$ value increases. Therefore,a higher $pH$ indicates a stronger base,and a lower $pH$ indicates a weaker base. Thus,statement $(iv)$ is correct.Combining these,statements $(ii)$ and $(iv)$ are correct.

Which of the following statements is correct about an aqueous solution of an acid and of a base?
$(i)$ Higher the $pH$,stronger the acid
$(ii)$ Higher the $pH$,weaker the acid
$(iii)$ Lower the $pH$,stronger the base
$(iv)$ Lower the $pH$,weaker the base
