QNEET-2016-Ch-1046: NEET 2016 Chemistry - Class 11 NEET-2016-Ch-1046 Solution: MY and \(NY_3\) two nearly insoluble salts have the same…
MY and two nearly insoluble salts have the same values of at room temperature. Which statement would be true in regard to MY and ? The salts MY and are more soluble in 0.5 M KY than in pure water. The addition of the salt of KY to solution of MY and will have no effect on their solubilities. The molar solubilities of MY and in water are identical. The molar solubility of MY in water is less than that of .
Multiple Choice Options
- A The salts MY and NY 3 are more soluble in 0.5 M KY than in pure water.
- B The addition of the salt of KY to solution of MY and NY 3 will have no effect on their solubilities.
- C The molar solubilities of MY and NY 3 in water are identical.
- D The molar solubility of MY in water is less than that of NY 3 .
Step-by-Step Verified Solution
MY _ M + + Y �
s s s
K sp = s.s = s 2
_ s = 6.2 _ 10 _ 13
= 7.87 _ 10 �7 mol L �1
NY 3 _ N + + 3Y �
s s 3s
K sp = s.(3s) 3 = 27s 4
6.2 _ 10 �13 = 27s 4
_ s = 3.89 _ 10 �4 mol L �1
Hence, molar solubility of MY in water is less than
that of NY 3 .
