Maria asks…the percent of silver in a solid mixture of sodium chloride and silver chloride?Nancy answers:Molar mass AgCl = 143.321 g/mol
% Ag = 107.868 x 100/ 143.321=75.26Joseph asks…Why must some solid remain in contact with a solution of a sparingly soluble salt in order to ensure equilibri?equilibrium??? thanks!!!Nancy answers:Lets look at a simple example with say, silver chloride
The equilibrium we are talking about is AgCl(s) Ag+(aq) + Cl-(aq)
At equilibria these will be at a
