1. The problem statement, all variables and given/known data What will the pH be by adding 1M HCL and 1M NaOH to pure water? 2. Relevant equations pH= -log[H+] 3. The attempt at a solution Well, If we form the reaction formula we get HCl + NaOH ---> H20 + NaCl This is a neutralizing reaction, so the net effect produces just water. Therefore the pH doesn't change. Is this logic right?
