Cu and Cu are the most common oxidation states of copper although Cu and Cu have also been reported. Cu tends to form stable compounds whereas Cu usually forms unstable compounds such as CuOH. One exception to this is Cu2O, which is much more stable. However, aside from this compound, compounds containing Cu have not been studied as extensively as Cu compounds due to their relative instability. This includes CuOH. WebOct 3, 2015 · "2.20 g" An alternative approach is to simply use the mole ratios that exist between the species that take part in the reaction, then use the molar mass of copper(II) hydroxide, "Cu"("OH")_2, to get the mass formed by the reaction. So, your sodium hydroxide solution contains C = n/V implies n = C * V n_(OH^(-)) = "0.450 M" * 100 * 10^(-3)"L" = …
