Question

When aqueous solutions of potassium nitrite and nitric acid are mixed, an aqueous solution of potassium nitrate and nitrous acid results. Write the net ionic equation for the reaction.

Answer 1

1.) C2H3O2-(aq) + H+(aq) ===> HC2H3O2(aq). K+ and Cl- are spectator ions. 2.) Ni(s) + Sn2+(aq) ===> Ni2+(aq) + Sr(s). NO3- is a spectator ion. 3.) 3Ag+ + PO4(3-)(aq) ===> Ag3(PO4)(s). Na+ and NO3-
