Copper(I) hydroxide is the inorganic compound with the chemical formula of CuOH. Little evidence exists for its existence. A similar situation applies to the monohydroxides of gold(I) and silver(I). Solid CuOH has been claimed however as an unstable yellow-red solid. The topic has been the subject of theoretical analysis. Copper(I) hydroxide would also be expected to easily oxidise to copper(II) hydroxide:
- 4CuOH + 2 H2O + O2 → 4Cu(OH)2
It would also be expected to rapidly dehydrate:
- 2CuOH → Cu2O + H2O
Solid CuOH would be of interest as a possible intermediate in the formation of copper(I) oxide (Cu2O), which has diverse applications, e.g. applications in solar cells.
