1. HCl is a strong acid, which means that it dissociates completely in water. What is the pH of a 0.01M solution of HCI? Show your work. Explanation: 0.010 M HCI consist of: 0.010M [H*] ions AND 0.010 M [CI] ions 0.010M [H*] + 0.010 M [CI] is not equal to total 0.010 M HCI. This is o.k. – molarity has no additive property. To obtain pH, you need [H* ] ions. We established that [H*] = 0.010 M. %3D Since pH = -log[H*] ions, then what is pH? %3D Your answer:

1. HCl is a strong acid, which means that it dissociates completely in water. What is the pH of a
0.01M solution of HCI? Show your work.
Explanation: 0.010 M HCI consist of: 0.010M [H*] ions AND 0.010 M [CI] ions
0.010M [H*] + 0.010 M [CI] is not equal to total 0.010 M HCI. This is o.k. – molarity has no
additive property.
To obtain pH, you need [H* ] ions. We established that [H*] = 0.010 M.

Since pH = -log[H*] ions, then what is pH?
