Interpretation Introduction

Interpretation:

The iodine involves in the oxidation–reduction titration to get a starch indicator from the stockroom is to be discussed.

Concept introduction:

 Polysaccharides are complex biomolecules that are composed of long chains of monosaccharides linked by the glycosidic bonds.

 A monosaccharide is the most basic form of carbohydrates that cannot be further converted into simpler units of another carbohydrate by hydrolysis.

 Oxidation is the addition of an electronegative element or the removal of an electropositive element in a chemical reaction.

 Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction.

 Starches are polysaccharides that have $\alpha -\text{glycosidic}\text{linkage}$.
