# Equivalent Weight Calculator using Double Decomposition Method

Double decomposition is also called as metathesis which is a chemical reaction between two compounds in which part of the first compound becomes united with part of the second compound. Use the below equivalent weight calculator that uses the double decomposition method to find the equivalent weight of the compounds and also for the component ions AB+CD--->AD+CB.

### Example:

Calculate the equivalent weight of CB(EB_{2}) through double decomposition method.

Weight of AB = 20

Weight of CB = 25

Equivalent weight of AB(EW_{1}) = 10

#### Solution:

Weight of oxygen (W) = 20

EW_{2}= (EW_{1} × weight of CB/weight of AB)

Equivalent weight of CB (EW_{2}) = 50 .
