# Pls solve Q). At , 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.
Therefore, option (1) is correct.
