Question

The product obtained on fusion of $BaS{O_4}$ and $N{a_2}C{O_3}$ is:
A. $BaC{O_3}$
B.BaO
C. $Ba{(OH)_2}$
D. $BaHS{O_4}$

Answer 1

Barium sulfate is an inorganic compound with chemical formula $BaS{O_4}$ . It is basically a white crystalline solid that is odorless and insoluble in water whereas sodium carbonate is an inorganic compound with chemical formula $N{a_2}C{O_3}$ and all forms of this compound are white in color.

Complete step by step answer:
Basically, barium sulfate is composed of barium cation and the sulfate anion. It is a sulfate salt of barium and is found as mineral barite. Moreover, it is a crystalline solid which is insoluble in water and alcohol but soluble in concentrated acids whereas sodium carbonate is commonly known as soda ash or washing soda. This organic compound is water-soluble and when dissolved in water, it forms carbonic acid and sodium hydroxide. Moreover, in its pure form, it is a white powder with no odor.
Now, when these two compounds are fused together, then $BaC{O_3}$ i.e. barium carbonate is formed. The reaction is as shown:
$BaS{O_4} + N{a_2}C{O_3} \to BaC{O_3} + 2NaS{O_4}$
Now, barium carbonate is a white solid generally precipitated from a solution of barium hydroxide and urea. It is toxic in nature and should be kept under low quality i.e. below $20\%$ . It reacts with hydrochloric acid to form barium chloride, water and carbon dioxide. The reaction is as shown:
$BaC{O_3} + 2HCl \to BaC{l_2} + {H_2}O + C{O_2}$

Hence, option A is correct.

Note:
Barium carbonate has many major applications in glass, bricks, ceramics and chemical industries. It is used as a rodenticide and also as a raw material for the manufacture of barium oxide (BaO) and barium peroxide $(Ba{O_2})$ .
