What it the basic formula for a double displacement equation?

Open in App

Solution

In a double replacement (displacement) reaction, two reactants combine to form two new substances, via switching the cations of each substance:

Let's illustrate this with a sample reaction:
We have our reactants :
1. $N a O H$
2. $H C l$

This will be a double replacement reaction, because there are two substances reacting that can both dissociate into their component ions in solution, which allows for the ions to move around and combine with another species.

Thus we would have the reaction

$N a O H (a q) + H C l (a q) \to N a C l (a q) + \begin{matrix} o r H_{2} O, w a t e r      H O H (l) \end{matrix}$
