What is the reducing agent in the following reaction

nika2105 [10]

Answer: $Fe^{2+}$ is the reducing agent

Explanation:

Oxidation reaction : When there is an increase in oxidation state number.

Reduction reaction : when there is a decrease in oxidation state number.

$5Fe^{2+}(aq)+MnO_4^-(aq)+8H^+(aq)\rightarrow 5Fe^{3+}(aq)+Mn^{2+}(aq)
+4H_2O(l)$

Fe has undergone oxidation, as its oxidation state is changing from+2 to +3.

Mn has undergone reduction, as its oxidation state is changing from +7 to +2.

The chemical agent which itself get oxidized and reduce others is called reducing agent. $Fe^{2+}$ is a reducing agent.

The chemical agent which itself get reduced and oxidize others is called oxidizing agent. $MnO_4^-$ is an oxidizing agent.

Oxygen, o, (number 8), sulfur, s, (number 16), and selenium, se, (number 34) have such similar chemical properties because?

irga5000 [103]

Oxygen (O), Sulphur (S) and Selenium (Se) have similar chemical properties because they all have the same number of electrons in their outermost shells.

Atoms with the same number of electrons in their outermost shells can be found in the same group.

A group consists of elements arranged in the same column (from top to bottom) on the periodic table. Elements on the same group have similar chemical properties.

Oxygen (O), Sulphur (S) and Selenium (Se) are in group eight. All three elements are highly electronegative and have 6 electrons in their outermost shell. They also carry ab charge of -2.
