Question- 1) When aqueous solutions of potassium acetate and hydrochloric acid are mixed, an aqueous solution of potassium chloride and acetic acid results. Write the net ionic equation for the reaction.
Use H+ for the hydronium ion, CH3COOH for acetic acid and CH3COO- for the acetate ion.
2) When aqueous solutions of sodium carbonate and copper(II) nitrate are combined, solid copper(II) carbonate and a solution of sodium nitrate are formed. The net ionic equation for this reaction is
3) When solid Mg metal is put into an aqueous solution of Sn(NO3)2, solid Sn metal and a solution of Mg(NO3)2 result. Write the net ionic equation for the reaction.
