5 0

Answer:

Alkylation reaction help in formation of thiol R-SH

<h2>Explanation:</h2>

Say lets take sodium hydrosulfide (NaSH) and alkyl chloride (R-Cl)/ any acid like chloroaceic acid or choloro or potassim acetates.

R-Cl + NaSH --> R-SH + NaCl

Such reactions are seen in the production of paper from wood pulp and in the production of organic compounds like thioglycolic acids (TGA)

JulsSmile [24]

Answer:

Total amount of alum lost = 0.5122 grams

Explanation:

Let the total volume of the solution be 100 mL

In 100 mL of solution, there is 2.63 gram of alum.

Out of this 100 mL solution, 42.5 mL is remaining.

Amount of alum in 42.5 mL solution is

\frac{42.5}{100} * 2.63 = 1.117\\ grams

Now the amount of alum lost is 2.63 -1.117 = 0.5122 grams
