Explain how the two acid salts of phosphoric acids are formed from the reaction of \(\mathrm{H}_{3} \mathrm{PO}_{4}\) with \(\mathrm{NaOH},\) and name them.
Problem 32
Silver bromide is "insoluble." What does this mean about the concentrations of \(\mathrm{Ag}^{+}\) and \(\mathrm{Br}^{-}\) in a saturated solution of AgBr? What makes it possible for a precipitate of \(\mathrm{AgBr}\) to form when solutions of the soluble salts \(\mathrm{AgNO}_{3}\) and \(\mathrm{NaBr}\) are mixed?
