Question

I: A salt whose water solution has a $p H$ of 5 is basic.
II: A solution having a $p H$ of 5 has a higher concentration of $H_{3} O^{-}$ ions than of ${O H}^{-}$ ions.

Open in App

Solution

Since, $p H < 7 \Rightarrow$ Acidic
$∵ H^{+} > 10^{- 7} M$
and Acidic $(p H \approx 5)$ solution has more $H_{3} O^{+}$ than ${O H}^{-}$ then only it is considered as acid.
