a) To make an acid solution, 6.8 x 10-3 mole of a strong acid (6.8 x 10-3 mole H3O+) is
dissolved in water to give a 550 mL solution. What is the pH and [OH-] of the solution?
b) 150 mL of water is added to 50 mL of the solution produced in question 3. Calculate the
new pH of the solution.
a.
(H3O^+) = 6.8E-3/0.550 = ?
Convert that to pH and to pOH and to OH^-
b
Assuming the volumes are additive (technically they are not), then
new (H3O^+) = old (H3OY+) x (150/200) = ?
Convert to pH.
