Question

write a balanced equation for the reaction of koh and cu(no3)2. express your answer as a chemical equation. identify all of the phases in your answer. enter noreaction if no precipitate is formed.

Explanation:

Step1: Write the reactants and predict products

Potassium hydroxide ($KOH$) and copper - nitrate ($Cu(NO_3)_2$) are both aqueous solutions. They undergo a double - displacement reaction. The products are potassium nitrate ($KNO_3$) and copper - hydroxide ($Cu(OH)_2$).
$KOH(aq)+Cu(NO_3)_2(aq)
ightarrow KNO_3(aq)+Cu(OH)_2(s)$

Step2: Balance the equation

For the potassium ($K$), copper ($Cu$), nitrogen ($N$), oxygen ($O$) and hydrogen ($H$) atoms to be balanced, we need 2 moles of $KOH$.
$2KOH(aq)+Cu(NO_3)_2(aq)
ightarrow 2KNO_3(aq)+Cu(OH)_2(s)$

Answer:

$2KOH(aq)+Cu(NO_3)_2(aq)
ightarrow 2KNO_3(aq)+Cu(OH)_2(s)$
