Solubility products constants (K(sp)) o...

Solubility products constants `(K_(sp)) ` of salts of types `MX, MX_2,M_3X ` at temperature T are `4xx 10^(-8) 3.2 xx 10^(-14) and 27 xx 10 ^(-15) ` respectively. Solubility `("moldm" ^(-3) ) ` of the salts at temperature T are in the order :

A

`MX gt MX_2 gt M_3X `

B

` M_3X gt MX_2gt MX `

C

` MX_2gt MX`

D

` MX gt M_3X gt MX_2`

Text Solution

Verified by Experts

The correct Answer is:
D
` K_(sp) " of MX " =4 xx 10 ^(-8) , S_1 = 2xx 10 ^(-4) M`
` K_(Sp) " of " MX_2 = 3.2 xx 10 ^(-14) , S_2 =2 xx 10 ^(-5) M`
` K_(sp) " of " M_3X =27xx 10 ^(-15) , S_3 ~~ 10 ^(-4) M`
` S_1 gt S_3 gt S_2`
