CuO copper oxide is not soluble in water so it will not dissociate OH- ions so how will we categorize it as base???? As to be a base it must dissociate OH- ions in aqueous solution but copper oxide will not. so all bases must be alkali to be a base??????

14th International Conference on the Properties of Water and Steam in Kyoto 492narrow and in the current experiments it was maintained by using deoxygenated solutions and added copper metal to maintain a controlled, slightly reducing ORP.. As an example of how experimental solubility data are treated in the present study and how the solubility varies as a function of pH, consider the equilibria involved in the dissolution of cuprous oxide in aqueous solutions: 0.5 Cu2O + H+ Cu+ + 0.5 H2O (1) 0.5 Cu2O + 0.5 H2O Cu(OH)0 (2) 0.5 Cu2O + 1.5 H2O Cu(OH)2- + H+ (3) [CuI,]total = m{Cu+} + m{Cu(OH)0} + m{Cu(OH)2-} = Ks0(m{H+}) + Ks1 + Ks2/(m{H+}) (4) where m{ } is the molality of a given species. For the sake of simplicity, activity coefficients are ignored in Eq. (4), but are considered in the actual data treatment. By regression analysis of the measured total copper concentration, [CuI,]total, as a function of m{H+} at each tempe
