Vedclass · Answer

(B) The $pH$ scale measures the acidity or alkalinity of an aqueous solution.For acids,the $pH$ value is inversely proportional to the concentration of hydrogen ions $(H^+)$. $A$ lower $pH$ indicates a higher concentration of $H^+$ ions,meaning a stronger acid. Therefore,statement $(ii)$ is correct: Higher the $pH$,weaker the acid.For bases,the $pH$ value is directly proportional to the concentration of hydroxide ions $(OH^-)$. $A$ higher $pH$ indicates a higher concentration of $OH^-$ ions,meaning a stronger base. Conversely,a lower $pH$ indicates a lower concentration of $OH^-$ ions,meaning a weaker base. Therefore,statement $(iv)$ is correct: Lower the $pH$,weaker the base.Thus,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
