Question

How to Identify what element Is:
i) Oxidized
ii) Reduced
iii) Oxidizing Agent
iv) Reducing Agent

Chemistry, Grade 10, Chapter 1.

Answer 1

Hi there,

☆The element which loses the electron increase its oxidation state and cosider as reducing agent

as example

■Fe => Fe2O3

● Iron element oxidation state is zero , in ferric oxide oxidation state of iron is +3 increases so its oxidized and it is a reducing agent

☆The element which ganing electrons , oxidation state dicreases and consider as oxidizing agent

◇As example

●CuSO4=> Cu

■Copper oxidation state in copper sulphate is +2 , and in copper element is zero , the oxidation state dicreases so it is reduced and become oxidizing agent

♡ Hope the answer is helpful

If u satisfied plz mark it as brainliest answer

Answer 2

Explanation:

i) Oxidized & (ii) Reduced.

First we have to know what is Oxidation & reduction reaction ?

Oxidation is loss of electrons

$Reductant \rightarrow product + electrons$

$\implies$ That means Oxidation number increases.

Reduction is gain of electrons

$oxidant + electron \rightarrow Product$

$\implies$ That means Oxidation number decreases.

Now, take this reaction

$Fe_2o_3 + 3co \rightarrow 2Fe + 3co_2$

Observations:

here, $Fe_2o_3$ is reduced to Fe as oxygen atoms are reduced so, reduction reaction takes place.

$\implies$ $3co$ is oxidized to co2 as it gains oxygen atoms , so oxidation reaction takes place here.

(iii) Oxidizing Agent & iv) Reducing Agent

A reducing agent is that substance which causes another substance to reduce in the chemical or redox reaction.

$\implies$ Reducing agent oxidation number changes and increases, then its an reducing agent.

A oxidizing agent is that substance which causes another substance to oxidize in the chemical or redox reaction.

$\implies$ Oxidizing agent oxidation number changes and decreases, then its an oxidizing agent.

Example :

$zn + cu^{2+} \rightarrow zn^2+ + cu$

$\implies$ zinc(zn) Reducing agent.

$\implies$ $cu^{2+}$ oxidizing agent.

$\implies$ $zn^2+$ Oxidized product

$\implies$ $cu$ reduced product
