Answer ( 1 )
Cr^2+ + H_2 MoO_4 – > Cr^3+ + Mo
Redox Reaction:
Redox response is a sort of response wherein oxidation and decrease happen at the same time.
The redox response can be separated into two sections oxidation half and decrease half.
Answer and Explanation:
The following is the given response:
Cr2++H2MoO4→Cr3++Mo
Oxidation half-response
Cr2+→Cr3+
• Balancing Charge:
Cr2+→Cr3++e−
Presently,
Decrease half-response
MoO2−4→Mo
Adjusting the decrease half-response we get,
MoO2−4+8H++6e−→Mo+4H2O
Presently,
Including both the conditions so that the electrons get counterbalanced.
6Cr2++H2MoO4+6H+→6Cr3++Mo+4H2O
