Question

Calculate the H₃O⁺, OH^- and pH of each of the following solutions:

i) 1.02g of H₂SO₄ diluted to 250ml of solution (assume a diprotic acid)

ii) 2.00mL of 0.500 M perchloric acid, HClO₄, diluted to 50.0 mL with water (assume that the volumes add!)

iii) 4.50 mL of concentrated sodium hydroxide solution (8.5M) diluted to 12.5 L with water

iv) 350 mL of an aqueous solution that is 0.20 M in NaCl and 0.15 M in MgCl₂. For this question, also calculate [Cl^-].
