Question

write the products obtained when Na2 So4 is hydrolyzed that is, react with water?​

Answer 1

Answer:

Cachets are also Known as *

Answer 2

The inorganic compound sodium sulfate, as well as other similar hydrates, has the formula Na2SO4

. Most of those forms are white solids that are extremely water soluble. It is mostly used in the making of detergents and the pulping of kraft paper.

Complete answer:

A molecule of water is attached to a product in a chemical reaction known as hydrolysis. When this happens, both the substance and the water molecule will break into two. One fragment of the target or parent molecule gains a hydrogen ion in such reactions.

First, we have to write the equation as per the given question.

Na2SO4(s)+H2O(l)

. That is sodium sulfate +

water.

So, when we look at Na2SO4

, sodium is a metal, and then SO4

, S

and O

are non-metals. The sulfate ion is called a polyatomic ion.

We look up sodium on the periodic table. It is in Group 1

that means it’s ionic charge is going to be a +1

, and then SO4

, the sulfate ion has 2

minus charges.

We take solid sodium sulfate and liquid water, and solid dissolves, and it dissociates into its ions

So, we got

Na2SO4(s)+H2O(l)→2Na+(aq)+SO2−4(aq)

.

The solid dissolved in water, and we got aqueous Na+

and aqueous SO2−4

. Because we mentioned aqueous in the equation, we don't need to write H2O

on the right side of the equation.

Therefore, the answer is Na2SO4(s)+H2O(l)→2Na+(aq)+SO2−4(aq)

.
