Neco Model Questions Vol1 2021 Chemistry Question 6
Practice objective / multiple choice question 6 from the 2021 Neco Model Questions Vol1 Chemistry examination.
Silver chloride (\(AgCl\)) has a solubility of \(1.33\times10^{-5}\,\text{M}\) in pure water at 25 °C. The same solid is placed in a solution that already contains \(0.010\;\text{M}\) NaCl and \(0.001\;\text{M}\) ammonia (\(NH_3\)). Silver ions form the complex \([Ag(NH_3)_2]^+\) with a formation constant \(\beta_2 = 1.6\times10^{7}\). Assuming the ammonia concentration remains essentially unchanged, calculate the equilibrium concentration of free \(Ag^+\) ions.
