Question

What is redox reaction? Give an example, why is the melting point of ice formed from tap water is below 0°c?​

Answer 1

Answer:

Redox reactions are chemical reactions involving simultaneous reduction of one substance (gain of electrons) and oxidation of another substance (loss of electrons).

These reactions are always coupled.

One reactant undergoes oxidation and another is reduced.

An example :

Cl2 + 2KI -------> 2KCl + I2

Here Cl2 is reduced and KI is oxidized.

Tap water contains many impurities and minerals.

Presence of impurities in water makes it a simple solution. Such solutions undergo depression in freezing point/melting point.

As a result of this depression, tap water melts below 0°C.

Answer 2

$\huge{\sf{\underline{AnswEr:-}}}$

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. The formation of hydrogen fluoride is an example of a redox reaction. We can break the reaction down to analyze the oxidation and reduction of reactants.
