OA it is a redox reaction
OB.It is a fast reaction
OC it is a double displacement reaction
Op None of these
Clear Selection​

Answer 1

Answer:

A. it is a redox reaction. I think it is the true answer

Answer 2

C) It is a double displacement reaction.

• Double displacement reactions are those in which the products are formed by exchanging one component from each of the two reacting species.
• The cations and anions of two distinct compounds swap positions during this reaction, creating two distinct molecules.
• A white precipitate of barium sulphate is produced when sodium sulphate solution is mixed with an aqueous solution of barium chloride.
• The salt is a sulphate if the white precipitate still remains insoluble in strong hydrochloric acid.
• A white precipitate of barium sulphate is produced almost quickly after mixing a solution of barium chloride with sodium sulphate. This product is insoluble, indicating that the reaction is irreversible.
• A double displacement reaction is one that occurs when sodium sulphate and barium chloride react.

Hence, option C is correct.
