Calculate the pH of solutions with the following concentrations.
A: [H3O+] = 1×10−12 M
Express your answer using one decimal place
B: [OH−] = 1×10−5 M
Express your answer using one decimal place.
C;
3.00×10−3 mol of HBr are dissolved in water to make 16.0 L of solution. What is the concentration of hydroxide ions, [OH−], in this solution?
Express your answer with the appropriate units.
D:
8.00 g of NaOH are dissolved in water to make 4.00 L of solution. What is the concentration of hydronium ions, [H3O+], in this solution?
Express your answer with the appropriate units.
E:
A solution has [H3O+] = 8.0×10−6 M . Use the ion product constant of water
Kw=[H3O+][OH−]
to find the [OH−] of the solution.
Express your answer to two significant figures.
F:
A solution has [OH−] = 1.3×10−2 M . Use the ion product constant of water
Kw=[H3O+][OH−]
to find the [H3O+] of the solution.
