Answer 2

Order of pH of substance 0.1 M HCI.0.1 M NaOH, Pure water, NaCl solution

Explanation:

Correct Option (a) 0.1 M HCl < Pure water = NaCl solution < 0.1 M NaOH

pH of the solution indicates its acidic or basic nature.

pH of acids is always less than 7. It can be said that lesser the pH, stronger the acid.

pH 7 indicates neutral solution like water.

pH value greater than 7 indicates the basic nature of solution. Greater the pH value, stronger the basic nature.

Here,

0.1 M HCl is highly acidic so it will have a low pH value.

pH of pure water and NaCl solution will be 7 because both are neutral.

0.1 M NaOH is a strong base so it will have pH value of more than 7.
