Hi,

Reaction 1:

Barium Sulphate + Hydrochloric acid -> Barium Chloride + Sulphuric Acid

Reaction 2:

Barium Chloride + Sulphuric Acid -> Barium Sulphate + Hydrochloric acid

How do i know which of the reaction is true, as both reaction may be able to react

Think about BaSO₄ solubility.

it is insoluble, but what got to do with it? $:-\$

the end product might give a ppt in reaction 2, and a clear solution in reaction 1..

No. The only reaction that takes place in your solution is BaSO₄ precipitation. Once it precipitate, it will not magically dissolve just to reverse the reaction

(Although I must admit that it all depends on the level of your chemistry course, as situation is slightly more complicated. But better don't ask about details till you understand basics.)

I got a nice crystals of BaSO4 crystallization of small amounts of BaSO4 from hot conc. HNO3
