Answer to Question #183777 in General Chemistry for Keke

Question

Solution questions

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.

5. How much water must be added to make a 0.50L of 1.0 mol/L sodium hydroxide? The stock solution you start with is 7 mol/L NaOH (aq).

Answer 1

1) Liquid _ Solid solution

2) Hard water

3). increases with temperature. 

4) And we could represent by the equation.

AgNO3(aq)+NaCl(aq)→AgCl(s)+NaNO3(aq)

Now of course, the sodium and nitrate ions are along for the ride, and do not participate in the net ionic equation.... Because in this instance they are merely carriers.....we could write the net ionic equation

$Ag^++Cl^−→AgCl(s)$

The nitrate and sodium are still present, but they remain as their aquated ions.
