Answer to Question #183856 in General Chemistry for Keke

Question

1.Mercury and silver is an example of which solution combination

2. Water that contains relatively large concentrations of ions that from insoluble compounds with soap is referred to as?

3. The solubility of a solid in water always

4. What is the net ionic equation for the reaction of an aqueous solution of sodium chloride with an aqueous solution of silver nitrate.

Answer 1

1. Solid Solid solution

2. Hard water

3. Increase with increase in temperature

4.  AgNO3(aq) + NaCl(aq) AgCl(s) + NaNO3(aq)

Based on the given balanced molecular equation, the precipitate that forms is AgCl. It is indicated by the (s) next to its chemical formula. Therefore, we only include the silver and chloride ions when writing the following net-ionic equation.

 

Net ionic equation:Ag(aq)+Cl(aq)→AgCl(s)

The sodium and nitrate ions do not participate in the precipitation reaction and are spectator ions.
