An acid solution of pH = 6 is diluted hundred times. The pH the solution becomes :
A.6.95✓ Correct
B.6
C.4
D.8
Explanation
When an acid solution is diluted 100 times its H becomes th 1 100 of the original H [H+] 6 10 M . After dilution 8 H 10 M . By calculation pH = 8 However, pH of an acid solution cannot be greater than 7. Therefore, the answer is 6.95.
