From the substances CuO, Cu (OH) 2, HNO3, N2O5, H2SO4, write down the bases

From the substances CuO, Cu (OH) 2, HNO3, N2O5, H2SO4, write down the bases, divide them into soluble and insoluble. Write down the names of the bases.

We are given substances, copper oxide CuO, copper hydroxide bivalent Cu (OH) 2, nitric acid HNO3, nitric oxide pentavalent N2O5, sulfuric acid H2SO4. Of all the listed substances, we can classify only copper hydroxide as bases. Copper hydroxide belongs to insoluble bases. Has a bright blue color. Divalent copper hydroxide can decompose into copper oxide and water when exposed to high temperature.
