Question

20 mL of 0.032 M AgNO3 are mixed with 15.0 mL of 0.041 M of NaBr at 25 °C. (Ksp of AgBr = 5 x 10-13, at 25 °C). Then,

a) the precipitation of AgBr occurs, as the solution will be supersaturated with AgBr

b) AgBr will not be precipitated, as the solution will be unsaturated

c) the resulting solution will be just saturated with AgBr and no precipitation takes place

d) no prediction can be done regarding the spontaneity of precipitation​

Answer 1

the resulting solution will be just saturated with AgBr and no precipitation takes place

is the ans

Answer 2

Ans: (c) The resulting solution will be just saturated with AgBr and no precipitation takes place is a correct option.
