Question

The simplest way to remove ammonium sulphate from the system is _____________

(a) precipitation

(b) dialysis

(c) chromatography

(d) purity checking

This question was posed to me by my college professor while I was bunking the class.

I need to ask this question from Enzymes Purification topic in section Enzymes Purification of Enzyme Technology

Answer 1

The correct answer is (b) dialysis

To explain I would say: Dialysis uses a cellophane tubing membrane which allows ammonium sulphate to enter and not the enzymes (proteins) which are high in molecular weight. Hence it is the simplest method. Precipitation, chromatography and purity checking are the steps involved in purification.
