C is right the properties of X are
Acidic,liberates CO2, precipitate in dil HCl
check NaHSO4 + Na2CO3--- Na2SO4 + H2O
Ba²+ + CO3²- --- BaCO3

The correct answer is C. NaHSO4 (Sodium hydrogen sulfate).

Here's why:

- A solution of NaHSO4 in water turns litmus red, indicating it's an acid.
- The gas produced when NaHSO4 is added to sodium carbonate (Na2CO3) is carbon dioxide (CO2), which turns lime water milky.
- NaHSO4 reacts with barium chloride (BaCl2) to produce hydrochloric acid (HCl).

The other options don't fit the description:

A. Na2CO3 (Sodium carbonate) is a base, not an acid.

B. NaHCO3 (Sodium bicarbonate) is a weak base, not a strong acid like NaHSO4.

D. Na2SO4 (Sodium sulfate) doesn't react with barium chloride to produce hydrochloric acid.

Myschool is wrong here. B is correct because it's only the compound that can evolve a gas that can turn lime wateq milky(i.e CO2). Not SO2.

the answer is A sha.
when Na2CO3 react with HCL it is going to form a base and CO2 .

The compound X is described as a crystalline salt of sodium that turns litmus red, indicating it's acidic. It produces a gas that turns lime water milky when added to sodium carbonate, which suggests the gas is carbon dioxide. This is a characteristic reaction of a carbonate or bicarbonate. When X is added to barium chloride solution, it gives hydrochloric acid, which indicates the presence of a chloride ion.

Given these properties, the correct answer is **B. NaHCO3** (Sodium bicarbonate). Sodium bicarbonate reacts with acids to produce carbon dioxide gas, and it also reacts with barium chloride to produce hydrochloric acid.
