Question

Minimum ph is shown by which solution ?
0.1 M CuSO4
0.1 M NaCl
0.1 M Na2O
0.1 M Na2SO4​

Answer 1

Answer:

Nacl have Minimum ph shown by solution

Answer 2

• From the given question the correct option is 0.1 M CuSO4.

• The minimum pH showed by the 0.1 M CuSO4 solution.

• As we know that the pH of  0.1 M CuSO4 is 4.5.

• It means that copper sulfate is acidic in nature. sulphuric acid is a strong acid and cupric hydroxide is a weak base so hydrogen ion is more than hydroxyl ion in water due that the solution will be acidic in nature.

• As we know the pH of 0.1 M NaCl and 0.1 M Na2SO4​ is 7. And the pH of 0.1 M Na2O is 13.

• So the minimum pH of the solution as shown in the question is 0.1 M CuSO4.
