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:
-
H2SO4 - strong electrolyte
(NH4)2S - strong electrolyte
HClO - weak electrolyte -
a) molarity = (16.7/58.5*0.719) = 0.397 M
b) 0.5/2.85 = 0.175 M
