HCI is a strong acid. You measured the pH of a 0.1M HCI solution and its pH was 1.0. You diluted the solution so that its new concentration was 0.01M and measured its pH. What would you expect? O O pH = 1.0 since it is still a strong acid pH = 1.0 since [H3O+] is 0.01M pH = 2.0 since [H3O+] is 0.01M pH >1.0 but can't be known exactly

HCI is a strong acid. You measured the pH of a 0.1M HCI solution and its pH was
1.0. You diluted the solution so that its new concentration was 0.01M and measured
its pH. What would you expect?
pH = 1.0 since it is still a strong acid
pH = 1.0 since [H3O+] is 0.01M
pH = 2.0 since [H3O+] is 0.01M
pH >1.0 but can't be known exactly
