The Equivalent Weight of Sulphuric Acid

The Equivalent Weight of Sulphuric Acid Is?

The equivalent weight of sulphuric acid is 49u.

Explanation: –

The formula for equivalent weight, which is the ratio of molecular mass to the number of replacement hydrogen, will be used to determine the equivalent weight of a specific compound. We will solve this problem by using the general formula and the atomic masses of elements from the periodic table.

Molecular formula of Sulphuric acid is H₂SO₄

The periodic table tells us that the atomic masses of Hydrogen, Sulphur, and Oxygen are as follows: –  

Atomic mass of Hydrogen (H) = 1u

Atomic mass of Sulphur (S) = 32u 

Atomic mass of Oxygen (O) = 16u

So, using the above atomic mass the molecular mass of H₂SO₄ is:
= (2×Atomic mass of H) + (1×Atomic mass of S) +(4×Atomic mass of O) 

= (2×1u) +(1×32u) +(4×16u) 

= 2u+32u+64u=98u

We know that the expression for an acid’s equivalent weight is as follows: 

Sulfuric acid has two hydrogen atoms that can be replaced.

If we change the values in the expression above, we get

As a result, Sulphuric acid’s equivalent weight is 49u.

The equivalent weight of a reactive polymer is the mass of the polymer with one reactivity derivative 

It’s especially essential for ion-share polymers (also known as ion-exchange resins): one version of an ion-exchange polymer can share one mole of single charged ions, but only half a mole of doubly charged ions.
