(aq) х Х Naßr Nat+Br CuBr Cut → + Br (aq) Shown above is the chemical equation for the dissolution of the slightly soluble salt CuBr Its Ky value in pure water was experimentally determined. CuBr was found to be much less soluble in a 0.001M NaBr solution than in pure water. Which of the following correctly explains the decrease in solubility of CuBr in 0.001 M NaBr? x The concentration of water is much less in the NaBr solution than in pure water, reducing the rate of dissolution of the salt. The presence of Nations in the solution inhibits the dissolution of salts. The presence of additional Br already in the solution decreases the value of the K for CuBr, causing the solubility to decrease. The presence of additional Brions already in the solution means equilibrium will be reached when much less CuBr has dissolved. D
