Answer:
The amount of anhydrous crystal are coming out of the solution when this is cooled from 80°C to 30°C are 5 kg of A
Explanation:
A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent, and knowing the solubility of component A at 80°C it is possible to know their amount, thus:
10Kg of water × = 8 kg of A
The maximum concentration that water can dissolve at 30°C is:
10Kg of water × = 3 kg of A
Thus, the amount of anhydrous crystal are coming out of the solution when this is cooled from 80°C to 30°C are:
8 kg of A - 3 kg of A = 5 kg of A

The TLC analysis is aimed to verify the completion and the product of the reaction. potassium permanganate is then added to the TLC plate to detect the existence of double bond in the final product. Potassium permanganate reacts with the double bond and makes the spot yellow-brown.
Electrophilic addition is an exothermic reaction, in which a pi bond is turned into a sigma bond. The double bond in the alkene acts as a nucleophile. Halogens, halogen acids , hypohalous acids, sulphonic acid and water can be used as the electrophilic reagent. In this experiment, bromination of cholesterol is performed. The electrophilic attack of Br2generates acyclic bromonium ion. The addition gives a trans stereochemistry to the bromonium ion. As the Br-attacks the most substituted carbon in anti-periplanar fashion by SN2reaction, it would result in the inversion of configuration at that specific carbon.
