Question

Neutralisation of $HCl\left(aq\right)$ with $NaOH\left(aq\right)$ is an example of a/an reaction.

• A. oxidizing
• B. reducing
• C. redox
• D. non-redox

Answer 1

The correct option is D non-redox

$\stackrel{+1}{H}\stackrel{-1}{\mathrm{Cl}}+\stackrel{+1}{\mathrm{Na}}\stackrel{-2-1}{OH}\to \stackrel{+1}{\mathrm{Na}}\stackrel{-1}{\mathrm{Cl}}+\stackrel{+1}{H_2}\stackrel{-2}{O}$ Elememt Intial oxidation number Final oxidation number

H	+1	+1
O	-2	-2
Na	+1	+1
Cl	-1	-1

The oxidation number of all the species in the chemical reaction is the same on the products and the reactants side, this is a non-redox reaction.
