Question

$pH$ of an aqueous $NaCl$ solution at ${50}^{\circ }C$ should be:

• A. $7$
• B. $>7$
• C. $<7$
• D. $0$

Answer 1

The correct option is C $<7$

Hydrolysis of salt of [SA SB] is not possible and Solution is neutral in nature (pH = pOH = 7).

So, pH of the solution should be neutral that is 7.

But since the temperature is more than ${25}^{o}C$ so neutral pH will be less than 7 since $Kw$ increase.
