1. A solution has a [H+] of 0.20 M. Find the pH of this solution.
2. A solution has a [H+] of a 0.00200 M . Find the pH of this solution.
3. A solution has a [OH-] of 0.050 M. Find the pH of this solution.
4. A solution has [H+] = 2.35 × 10-3 M. Find the [OH-] for this solution.
5. A solution has pOH = 5.640. Find the [H+] for this solution. (Hint: Find pH first. Then use the formula [H+]= 10-pH to solve for [H+] )
