The ksp of AgCl is 1.8*10^-10. What would be the concentration of silver and chlorine ions in a solution of pure water and solid AgCl?

Question

The ksp of AgCl is 1.8*10^-10. What would be the concentration of silver and chlorine ions in a solution of pure water and solid AgCl?

a)1.3^10^-5 mol/L

b)1.8*10-10 mol/L

c)3.24*10-20 mol/L

d)None of these

Answer 1

K_sp=[Ag⁺][Cl^-],. This represents the product of their molar concentrations.If we set x=[Ag⁺}, then [Cl^-] is also x ans x²=1.8x10^-10 and x=(1.8x10^-10)^-.5=1.3x10^-5, choice a.
