Sample questions

Question 1

The solubility product, $K_{sp}$, of $\ce{PbCl2}$ is $1.6 \times 10^{-5}$. What is the molar solubility of $\ce{PbCl2}$ in 0.1 M $\ce{NaCl}$ solution?

Question 2

Assertion (A): For a strong acid and strong base titration, the pH at the equivalence point is always 7. Reason (R): The indicator used in such a titration should have a pKin value close to 7.

Question 3

A graph showing the variation of concentration of reactants and products with time for a reversible reaction, $\ce{A <=> B}$, initially starting with only reactant A, is given. Which of the following correctly represents the concentration changes over time? (Assume that concentration of A decreases exponentially to a constant value, while concentration of B increases exponentially to another constant value, and at equilibrium, both [A] and [B] are non-zero.)
