Classify these compounds as strong electrolytes, weak electrolytes, or nonelectrolytes

1.) Classify these compounds as strong electrolytes, weak electrolytes, or nonelectrolytes.

H2SO4
(NH4)2S
HClO

2.) Calculate the molarity of the following solutions.

a.) 16.7 g of NaCl in 719 mL of solution.
b.) 0.500 mol of NaOH in 2.85 L of solution.

Answer:

  1. H2SO4 - strong electrolyte
    (NH4)2S - strong electrolyte
    HClO - weak electrolyte

  2. a) molarity = (16.7/58.5*0.719) = 0.397 M
    b) 0.5/2.85 = 0.175 M
