The equivalent weight of acid can be defined as the ratio of the molecular weight of the acid to the basicity of acid. This equivalent weight of acid varies depending on the types of reactions it undergoes.

Check the formula for the equivalent weight of acid that is given below.

Equivalent weight of acid = Molecular weight of acid / Basicity.

**E _{w} = M_{w}/B**

Go through the simple steps below to calculate the equivalent weight of acid manually.

- Firstly, take the values of molecular weight of acid and basicity of acid from the given problem.
- Then, apply the formula of acid weight, i.e., E
_{w}= M_{w}/B. - Finally, you will get the answer for the equivalent weight of acid easily.

**Question: **Calculate the equivalent weight of Acid, if the molecular weight of acid is 30 and the basicity of Acid is 12?

**Solution:**

Given that, M_{w} = 30

B = 12

Look into the weight of the Acid formula,

**E _{w} = M_{w}/B**

Substitute the values in it.

E_{w} = 30/12 = 2.5

Therefore the Equivalent weight of Acid is 2.5
