detail is given below.

Explanation:

Chemical equation:

AuBr₃ + Cl₂    →       AuCl₃ + Br₂

Balanced chemical equation:

2AuBr₃ + 3Cl₂    →       2AuCl₃ + 3Br₂

The reactants of this chemical reaction are,

AuBr₃

Cl₂

The product of this chemical reaction is,

AuCl₃

Br₂

Reaction type:

The reaction type is single replacement reaction.

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

In a similar way chlorine replace the bromine and form gold(III) chloride and bromine gas.

the ratio of the conjugate base to the acid required to attain the desired ph.
