Given :

\begin{aligned} {XNa}_2 {HAsO}_3+{YNaBrO}_3+{ZHCl} \rightarrow & {NaBr} \\ & +{H}_3 {AsO}_4+{NaCl} \end{aligned}

The values of

{X}, {Y}

and

{Z}

in the above redox reaction are respectively

View answer and explanation

Correct option: C

3,1,6

Option C (3,1,6) is correct because it correctly balances the redox reaction, ensuring that the number of atoms of each element and the total charge are the same on both sides of the equation.
