Question

A litre of solution is saturated with AgCl. To this solution if `1.0 xx 10^(-4)` mole of solid NaCl is added, what will be the `[Ag^(+)]`, assuming no volume change
A. More
B. Less
C. Equal
D. Zero

Answer 1

Correct Answer - B
`{:(AgCl,rarr,"Ag"^(+),+,Cl^(-)),(,,x,,x):}`
After NaCl is added `K_(sp) = x xx (x +1 xx 10^(-4))`
That is why `Ag^(+)` will be less.
