1.

Which of the following species is more soluble in water ?A. `M(OH)_(3)` , `(K_(SP)=1xx10^(-35))`B. `M(OH)_(2)` , `(K_(SP)=1xx10^(-30))`C. MOH , `(K_(SP)=1xx10^(-28))`D. MOH , `(K_(SP)= 1xx10^(-26))`

Answer» Correct Answer - A
S of `M(OH)_(3)=4sqrt((K_(SP))/(27))=4sqrt((10^(-35))/(27))`
`= 7.8xx10^(-10)`
S of `M(OH)_(2) = 3sqrt((K_(SP))/(4))`
`S of MOH= sqrt(K_(CP))`
