Step 1  Ionic compounds containing hydroxide ions are insoluble unless they contain an alkali metal ion, or a bsrium, strontium, or calcium ion. Because hydroxide reacts with copper, it will form a solid precipitate.  2KOH(aq)+Cu(NO3)2(aq)→2KNO3(aq)+Cu(OH)2(s)  The precipitate is copper (II) hydroxide, see work for the balanced equation.

Step 1  When potassium hydroxide reacts with copper nitrate, a pale greenish blue precipitate of copper hydroxide is formed along with the formation of potassium nitrate.  This reaction is a type of precipitation reaction because a precipitate is being formed.  The equation for the reaction between the two follows: 2KOH(aq.)+Cu(NO3)2)aq.)→2KNO3(aq.)+Cu(OH)2(s)  By Stoichiometry of the reaction:  2 moles of potassium hydroxide reacts with 1 mole of copper nitrate to produce 2 moles of potassium nitrate and 1 mole of copper hydroxide.
