Question

Identify the precipitate (if any) that forms when KOH and Cu(NO3)2 are mixed.

Answer 1

you're doing a double displacement reaction. check if the combinations of either of the new products are insoluble (low Ksp value)

you need a Ksp table for this.

Answer 2

Cu(OH)2. Just find a solubility rule chart and switch the ions.

Answer 3

You end up with KNO3 and Cu(OH)2 but only the copper(II) hydroxide is insoluble

Answer 4

Which makes it the precipitate.
