could you help me to explain why doesn't the pH change when we dilute it with water? thanks

When something is diluted you change both the concentrations of acid and base but the ratio is still the same

When you dilute something you are just spreading it out more

An acid diluted DOES change the pH.
A base diluted DOES change the pH.
For example, 0.1 M HCl has a pH of 1.
Dilute that by a factor of 2 and the concn = 0.05. The pH of that solution is -log(0.05) = 1.30
