10 6 m hcl is diluted to 100 times
Asked by admin @ in Chemistry viewed by 260 People
If a solution of 10^-6 m hcl is diluted 100 times the ph of solution is
Answered by admin @
A solution with pH 6 has concentration 10-6 M
If it is diluted 1000 times, it becomes 10-6/1000 = 10-9 M
Water has a pH = 7. Thus, [H3O+] in water = 10-7 M
Now, the [H3O+] in dilute acidic solution will approach 10-7 M. The concentration can not become less than 10-7 M due to dissociation of water to H3O+.
So, pH of resulting solution will be approx. 6.96.
