Calculating pH from Equation with Water
How do you calculate the pH of an acid when you are given it's volume added to the volume of water? For example, given 10ml 15M HBr + 500ml H20, what is the pH of HBr?

Re: Calculating pH from Equation with Water
You would use the molarity equation M1V1=M2V2 since you know the first molarity and the first and second volume you can find the second Molarity to give you the concentration of the [H3O+]. From there you use the pH = -log ([H3O+])
