Question
An acid solution with pH = 6 at 25oC is diluted by 102 times. The pH of solution will:
Options
A.Decrease by 2
B.Increase by 2
C.Decrease by 0.95 approximately
D.Increase by 0.95 approximately
Solution
[H+] = 10-6 at pH = 6
If [H+] are diluted to 102 times, the new [H+] > 10-7 as we get [H+] from water. Thus pH of solution will be in between 6 to 7 or approximately 6.95.
If [H+] are diluted to 102 times, the new [H+] > 10-7 as we get [H+] from water. Thus pH of solution will be in between 6 to 7 or approximately 6.95.
