Question

Pls answer the question​

Answer 1

7

Step-by-step explanation:

pH =-log[H+] and

H+ ion concentration of pure water is 10^-7 making pH value of water =7

Actually this change with temperature as water can get ionised more or less on temperature.

This value is correct only at 25 °C

Acids have higher H+ ion concentration than water so the pH value should be lower than 7.

So answer is 3
