Question

What do you understand by redox reactions? Explain oxidation and reductionin terms of loss or gain of electrons

Answer 1

ANSWER-

◆ The reaction in which one reactant get Oxidized while gets reduce is called REDOX REACTION.

◆ OXIDIZING = The reaction in which gain of oxygen and loss of hydrogen.

◆ REDUCING = The reaction in which gain of hydrogen and loss of oxygen.

Answer 2

$\bold{ \underline{ \red{REDOX \: \: REACTION \: \: \:}}}$➡

$\bold{Redox \: \: reaction \: \: is \: \: also \: \: known \: \: as}$
$\bold{Oxidation - Reduction \: \: reaction. \: It \: \: is }$
$\bold{a \: \: type \: \: of \: \: chemical \: \: reaction \: \: which}$
$\bold{involves \: \: transfer \: \: of \: \: electrons. \: Every \: \: }$
$\bold{redox \: \: reaction \: \: consists \: two \: \: parts.}$
$\bold{These \: \: two \: \: are : - \: Oxidation \: \: and \: \: }$
$\bold{Reduction. \: In \: \: a \: \: redox \: \: reaction ,\: there }$
$\bold{is \: \: a \: \: transfer \: \: of \: \: electrons \: \: from \: \: the}$
$\bold{substance \: \: being \: \: oxidized \: \: to \: \: the}$
$\bold{substance \: \: being \: \: reduced.}$

$\bold{ \underline{ \red{EXAMPLES \: \: }}}$ ➡

$\bold{(i) \: \: CuO + H_2 - - > Cu + H_2O} \\ \\ \bold{(ii) \: \: MnO_2 + 4HCl - - > MnCl_2 + 2H_2O + Cl_2} \\ \\ \bold{iii \: \: ZnO + C - - > Zn + CO}$
