Consider an amphoteric hydroxide, M(OH)2(s). where M is a generic metal. Estimate the solubility of M(OH)2 in a solution buffered at pH = 7.0, 10.0, and 14.0. Copper(l) ions in aqueous solution react with NH3(ag) according to Calculate the solubility (in g- L-1) of CuBr(s) (Kgp = 6.3 times 10-9) in 0.88 M NH3(aq). The formation constant of [M(CN)2] is 5.30 times 1018, where M is a generic metal. A 0.160-mole quantity of M(NC>3) is added to a liter of 0.710 M NaCN solution. What is the concentration of M + ions at equilibrium?
