Znso4 is an organic Compound with the chemical formula znso4 and compound name is zinc sulphate.

zinc sulphate are prepared by reaction between zinc and sulphuric acid after reaction it give zinc sulphate as a product.

In this article, we will discuss about preparation of zinc sulphate, and also reaction between zinc and sulphuric acid. if this reaction is done, it is given zinc sulphate as a product.

So, hold your seat and be with the end of guide.

So, You could get, valuable information out of it.

Preparation of Znso4

zn + h2so4

You know that, when zinc react with sulphuric acid (dil) then it is given zinc sulfate and hydrogen is removed. the reaction is as below;

Zn + H2SO4 – ZnSO4 + H2

Zinc + Sulphuric – Zinc Sulphate + Hydrogen

Zn h2so4



Zn = zinc

H2SO4 = sulphuric acid (dil)

After reaction zinc and so4 is add together and it is given (zinc sulphate) (aq) as a product.

In this reaction, hydrogen gas is removed because zinc does librate hydrogen gas when zinc react with dil sulphuric acid.


ZnSO4 – zinc sulfate(aq) (product)

H2 – hydrogen (gas)

Molar mass of znso4?

We know that,

the chemical name is zinc sulphate.

[Determine the molecular mass of znso4 = atomic mass of zn = 65 s = 32 o = 16u]

Molar mass of znso4 = atomic mass of zn + atomic mass of S + 4× atomic mass of O.


65u + 32u + 4× 16

65u + 32u + 64u


Thus, the molecular mass of zinc sulphate equal to 161u

na2s + znso4

First off all, You know that,

What is the chemical name of na2s?

the chemical name of na2s is sodium sulfide.

Sodium sulfide is a chemical compound with the formula na2s. It is colourless solid and properly soluble in water.

When the sodium sulfide react with zinc sulphate then the reaction then write the blance equation of sodium sulfide with zinc sulphate?

Znso4 + na2s – zns + Na2so4


write the state (s, liquid, gas) for each substance.

Znso4 (aq) + na2s (aq) – zns (l) + Na2so4 (aq)

Zn (2+) aq + S (2-) aq = ZnS (s)

When the sodium sulfide react with zinc sulphate then zns and Na2so4 is formed as a product.

So, the final product is Zns and Na2so4.
