Question

What would be the products for the reaction Br2 + KI →? (Just identify the correct products for the reaction. You do not need to balance the equation.) 1. BrI + K+ 2. I2 + KBr 3. I 1− + K+ 4. No reaction would occur.

Answer 1

Answer: The products of the reaction will be $I_2\text{ and }KBr$

Explanation:

Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.

The general chemical equation for the single displacement reaction follows:

$A+BC\rightarrow AC+B$

The given chemical equation follows:

$Br_2+2KI\rightarrow I_2+2KBr$

Bromine element is more reactive than iodine element. Thus, can easily replace iodine from its chemical reaction.

Hence, the products of the reaction will be $I_2\text{ and }KBr$
