Pls solve
Q). At 90 °   C , the pH of 0.1 M NaCl aqueous solution is :-
(1) < 7
(2) > 7
(3) 7
(4) 0.1

Dear Student,

When the temperature of the NaCl solution is increased, then the [H+] (hydrogen ion concentration) tends to increases as the hydrogen bonds breaks on increasing the temperature.
So, as the temperature is increased the pH will decrease.             pH = - log [H+]
Therefore, option (1) is correct.

Hope this information clears your doubts about the topic

Keep asking!!

Regards
