| Write the molecular, complete and concise ionic equation for the reaction between copper (II) chloride and potassium hydroxide.
This reaction refers to exchange reactions.
An exchange reaction is a reaction as a result of which complex substances exchange their constituent parts.
The exchange reaction proceeds to the end. if gas is formed, water or substance precipitates out.
CuCl2 + KOH = Cu (OH) 2 + KCl
The reaction proceeds to the end, as a precipitate is formed (Cu (OH) 2)
Let’s arrange the coefficients.
CuCl2 + 2KOH = Cu (OH) 2 + 2KCl
Cu ^ (2+) + 2Cl ^ (-) + 2K ^ (+) + 2OH ^ (-) = Cu (OH) 2 + 2K ^ (+) + 2Cl ^ (-)
Reducing similar terms in the right and left sides of the equation, we get:
Cu ^ (2+) + 2OH ^ (-) = Cu (OH) 2
