Question

The concentration of ag+ in a solution saturated with ag2c2o4(s) is 2.2 ✕ 10-4 m. calculate ksp for ag2c2o4. webassign will check your answer for the correct number of significant figures.

Answer 1

The Ksp for Ag2C2O4 is calculated as follows

write the equation for dissociation for Ag2C2O4

that is Ag2C2O4 -----> 2Ag^+ + C2O4 -

the concentration of C2O4 ^2- = 2.2 x10^-4 and that of Ag = 2 x(2.2 x10^-4)

Ksp =( Ag+)^2 (C2O4-)

that is ( 2x2.2 x10^-4) ( 2.2 x10 ^-4) = 4.26 x10^-11
