Question

what is observed what is observed when a solution of sodium sulphate is added to a solution of Barium Chloride taken in a test tube write equation for the chemical reaction involved and name the test tube of real Iron Man the type of reaction and this case

Answer 1

Answer:

Explanation:

When a solution of sodium sulphate is added to a solution of barium chloride, a white precipitate of barium sulphate will be formed immediately. This precipitate is insoluble in dilute hydrochloric acid (dil.HCl) and also insoluble in water. This type of reaction is called precipitation reaction as the Baso4 precipitate thus formed is of white colour.

The equation of the above mentioned reaction is given as follows:

Na2SO4 (aq) + BaCl2(aq) -------> BaSO4(s) + 2NaCl(aq)

Since, barium sulphate is insoluble in water, so it will precipitate as a solid, where as the sodium chloride will remain in solution.

Answer 2

During the first stage of Sodium Sulphate added with Barium Chloride, Barium Sulphate will be formed. It is ‘insoluble in hydrochloric acid’ which is dilute. It is also insoluble in water. This reaction is known as $\bold{\mathrm{BaSO}_{4}}$. It will be white in colour. This reaction comes under precipitation reaction.  

The equation of the above mentioned reaction is  

$\bold{\mathrm{Na}_{2} \mathrm{SO}_{4}(\mathrm{aq})+\mathrm{BaCl}_{2}(\mathrm{aq}) \rightarrow \mathrm{BaSO}_{4}(\mathrm{s})+2 \mathrm{NaCl}(\mathrm{ag})}$

Barium sulphate is insoluble in water. It will precipitate as a ‘solid’. The ‘sodium chloride’ will remain in solution.
