Question:
This equation represents the preparation of gold sol by
\[
2 \, \text{AuCl}_3 + 3 \, \text{CHO} + 3 \, \text{H}_2 \text{O} \rightarrow 2 \, \text{Au} + 3 \, \text{HCOOH} + 6 \, \text{HCl}
\]
This equation represents the preparation of gold sol by
\[
2 \, \text{AuCl}_3 + 3 \, \text{CHO} + 3 \, \text{H}_2 \text{O} \rightarrow 2 \, \text{Au} + 3 \, \text{HCOOH} + 6 \, \text{HCl}
\]
Show Hint
In redox reactions, identify the species being reduced (gaining electrons) and those being oxidized (losing electrons) to classify the reaction correctly.
