IntermediateMCQConceptual13.4k
A student has two separate saturated aqueous solutions at equilibrium: Beaker 1 contains solid calcium carbonate, \(\text{CaCO}_3\text{(s)}\), in contact with its ions, and Beaker 2 contains solid silver chloride, \(\text{AgCl(s)}\), in contact with its ions. A few drops of concentrated nitric acid, \(\text{HNO}_3\text{(aq)}\), are added to each beaker, significantly decreasing the pH of both solutions without noticeably changing the total volume. Which of the following predictions best describes the effect of decreasing the pH on the solubility of each solid?
