Question on finding pH
« on: August 15, 2005, 08:26:03 PM »
The question is:
What is the pH of 20.0mL of 0.050 M HCl
A. 1.30
B. 1.70
C. 2.60
D. 3.00

I'm not asking for you to do the work for me but to give me a formula or website where i can learn how to find it. Thanks ;)

pH = - log [H+]

You don't need the volume to solve this question.
