## Question:

In what molar ratio do you expect sodium hydroxide and copper (II) chloride to react?

## Double Displacement Reactions

Double displacement reactions, also known as metathesis reactions, happen when two reactants exchange their cations and anions, as demonstrated below.

$$AB_{(aq)} + CD_{(aq)} \rightleftharpoons AD_{(aq)} + CB_{(aq)}$$

A common example of this type of reaction is precipitation reactions. It is important to note that chemical reactions should be balanced before performing any necessary calculations.
