Gce Model Questions Vol1 2019 Chemistry Question 26
Practice objective / multiple choice question 26 from the 2019 Gce Model Questions Vol1 Chemistry examination.
A sparingly soluble salt AB₂ has a solubility product \(K_{sp}=4.0\times10^{-10}\) at 25 °C. (i) When \(0.010\) mol of \(A^{2+}\) is added to \(1.0\) L of water containing the salt, calculate the equilibrium concentration of \(B^{-}\) ions that originate from the dissolution of AB₂. (ii) The temperature is then raised to 35 °C, at which \(K_{sp}\) increases by 50 % (i.e. \(K_{sp}=6.0\times10^{-10}\)). Assuming no additional \(A^{2+}\) is added, determine the new concentration of \(B^{-}\) ions at equilibrium.
