A Level Chemistry 2017 Paper 1 Question 15 Solution - Exclusive
In this exclusive video we want to discuss the suggested solution for A Levels Chemistry (H2 Chemistry) 2017 Paper 1 Question 15.
Let's take a look at this question:
The topic tested in this question is on Solubility Product.
We can first write down the dissociation of sparingly soluble salt PbCrO4 and let x be the solubility of this salt.
So at equilibrium the concentration of Pb2+ and CrO42- will both be x.
We can then express the Ksp in terms of solubility and solve for Ksp since solubility x is known.
We can then compare the answer to the options and determine the answer is A.
