(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

You have a 1L of a 2M HCl solution. Assume that the HCl completely ionizes.

a) Calculate the pH of the solution right now.

b) You now add V litres of water to the solution.

Find the pH of the new dilute solution in terms of V.

2. Relevant equations

pH = -log[H]

3. The attempt at a solution

a) pH = -log(2) which is interestingly a negative number so I hope this is correct.

b) I'm not sure how you would do this part. Do we just find the new concentration in terms of V and then find the negative log of that? Don't we have to consider the autoionization of water?

Thanks!
