Vedclass · Answer

(C) $pH$ is a measure of the hydrogen ion concentration,where $pH = -\log[H^+]$.For basic solutions,a higher concentration of $OH^-$ ions corresponds to a higher $pH$.$1 \ M \ NaOH$ is a strong base that dissociates completely to provide a high concentration of $OH^-$ ions,resulting in a $pH$ of $14$.$1 \ M \ NH_3$ is a weak base with a lower $pH$ than $NaOH$.Distilled water is neutral $(pH = 7)$.Water saturated with chlorine is acidic due to the formation of $HCl$ and $HOCl$,resulting in a $pH Therefore,$1 \ M \ NaOH$ has the highest $pH$.
