Homework Statement


What will the pH be by adding 1M HCL and 1M NaOH to pure water?

Homework Equations


pH= -log[H+]

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?

Depends on whether you are expected to take ionic strength of the solution into effect, or not. That's typically at least undergraduate level though.
