Ionic equations
1. Which of the following acids is a weak electrolyte?
HNO3H2S HClO4 H2SO4HCl
2. The spectator ions in a reaction between lithium hydroxide and hydrochloric acid are:
Li+ and Cl-H+ and OH- Li+ and H+Li+ and OH-
3. The net ionic equation for the reaction between mercury(I) nitrate and potassium chloride does NOT include which of the following species?
Cl-NO3-Hg22+Hg2Cl2(s)
4. The balanced net ionic equation for the reaction between acetic acid and sodium hydroxide is:
H3O+(aq) + OH-(aq) = 2 H2O(l)
H+(aq) + C2H3O2-(aq) + OH-(aq) = C2H3O2-(aq) + H2O(l)
H+(aq) + OH-(aq) = H2O(l)
H+(aq) + C2H3O2-(aq) + OH-(aq) = C2H3O2-(aq) + H+(aq) + OH-(aq)
HC2H3O2(aq) + OH-(aq) = C2H3O2-(aq) + H2O(l)
5. The compound NH4NO3 is best classified as
a nonelectrolyte a strong base a molecular compounda strong electrolytea weak electrolyte
