Is CuOH2 soluble or insoluble

Answer 1

CuOH is not the formula of copper hydroxide, it is Cu(OH)2, where the 2 should be a subscript. It is a blue gelatinous solid formed when hydroxide ions are added to solutions of copper salts. It is insoluble, but decomposes in air to copper oxide and water.

Answer 2

Copper (ii) hydroxide is insoluble in water. This molecule has strong attraction between the copper and hydroxide ions. Thus, the bonds formed between water molecules and these ions are unable to separate the ions and dissolve them.
It depends on the solvent you're trying to use. Cu(OH)2 won't dissolve in water or ethanol, but it will in ammonia water and potassium cyanide solution.

Answer 3

All nitrites are soluble in water except silver(I) nitrite.

Hence, CuNO2 is soluble in water.

It is due to the low polarisability of nitrite ion that cuno2 has less covalent, and thus, more ionic character.
