Question

Consider the following unbalanced redox reaction:

MnO4 � (aq) plus Sb H2 (aq) yields Mn O2 (s) plus Sb (s)
What is being reduced?

Answer 1

is it Mn04

Answer 2

MnO4-

SbH3

MnO2

Sb
these are the options btw

Answer 3

First try balancing the equation

Answer 4

ok i did what was ur final answer im so confused that i need more guidance

Answer 5

just wait

Answer 6

a sec

Answer 7

ok

Answer 8

We'll delete one option first i.e SbH3

Answer 9

yes that is clear . wouldnt that be the oxidizing agent

Answer 10

But there is no SbH3 there in the qn right?

Answer 11

sorry i meant SB

Answer 12

what is the oxidizing agent in this equation

Answer 13

reducing agent is substance which get oxidized itself by giving electron

Answer 14

so Mn02 is the answer

Answer 15

right ?

Answer 16

I think so can you wait for sometime i'll check back to you after referring to some books thanks

Answer 17

ok

Answer 18

ok so this is simple. Keep this in mind
Reduction means there will be a decrease in the product from the reactant
Oxidation means there will be an increase in the product

Answer 19

So as far as the qustion is concerned, Mno4 gets reduced to MNO2 and Sbh2 to Sb. So both Sb and O2 get reduced. Since the options given to you do not have O2, go for Sb

Answer 20

and that makes the oxidizing agent to be mn04-

Answer 21

?

Answer 22

vice versa of agents
Oxidising agent Decreases and Reducing agent increases

Answer 23

so its MnO4

Answer 24

Have you understood? i think you are confused

Answer 25

OK I'll explain the entire thing with another example.

Answer 26

You need not learn any definition byheart, just understand these simple procedures that i tell you

Answer 27

So i said
Oxidising agent means there will be a decrease in the product
Reducing agent means there will be an increase in the product
