If Ksp of salt A3B is 2.7×10^-11 then solubility of salt will be?
Answers
Answer:
AB>A
3
B>AB
2
Explanation:
Let us assume that s
1
,s
2
,s
3
represents the solubility of AB,AB
2
and A
3
B respectively.
The expression for s
1
is s
1
=
K
sp
Substitute values in the above expression,
s
1
=
4×10
−8
=2×10
−4
M
The expression for s
2
is s
2
=
3
4
K
sp
Substitute values in the above expression,
s
2
=
3

3.2×10−14
=2×10
−5
M
The expression for s
3
is s
3
=
4
27
K
sp
Substitute values in the above expression.
s
