Question

Acidity in sugarcane juice is removed by adding:
A. ${\text{Ca(OH}}{{\text{)}}_{\text{2}}}$
B. ${\text{C}}{{\text{O}}_{\text{2}}}$
C. ${\text{S}}{{\text{O}}_{\text{2}}}$
D. ${{\text{H}}_{\text{2}}}{\text{O}}$

Answer 1

Hint: Acidity refers to the amount of acid present in a particular substance. Usually, a base is employed to neutralize an acidic substance. For example, in the case of acid refluxes we generally take eno, this eno contains some of the bases which neutralize the acidity. The neutralization process is nothing but a reaction between hydroxide ion (from the base) and hydrogen ion (from acid) to give water. Thus, by employing a base acid is being neutralized.

Complete step by step answer:
Sugarcane juice is a bit acidic and this acidity is due to the presence of alpha-hydroxy acids like glycolic acid, etc. and some impurities. To neutralize these acids we require a base.
${\text{Ca(OH}}{{\text{)}}_{\text{2}}}$ is a base which can be employed for the neutralization of the acid present in the sugarcane juice.
On the other hand ${\text{C}}{{\text{O}}_{\text{2}}}$, ${\text{S}}{{\text{O}}_{\text{2}}}$ are gases and not quite basic.
Water is a neutral substance and cannot neutralize an acid.
Therefore, out of the given options, the only base we have is ${\text{Ca(OH}}{{\text{)}}_{\text{2}}}$ which can be used for the neutralization of sugarcane juice.

So, the correct answer is Option A.

Note:
Sugarcane juice is sweet, relishing, and extremely nourishing for the body.
Sugarcane is known to have a variety of medicinal uses in ancient Indian medicine and is packed with vital nutrients.
Sugarcane is used to strengthen boon, boost immunity, enhance digestion, and relieve stress.
It is an excellent detox for the liver.
Sugarcane juice is used to make jaggery, molasses, rum, biofuels, etc.
India is the world’s largest producer of sugarcane followed by Brazil.
