This is achieved by passing H 2 S gas in the presence of strong electrolyte HCl, which has a common ion (H +) with H 2 S. Due to the common ion effect, the dissociation of H 2 S is suppressed and thus, the concentration of `"S"^ (2-)` ions decreases. Outline the stages of recombinant DNA technology.

(3 marks), b) By the same logic, what would you expect to happen to the translated DNA sequence if an exon was modified by a mutagen. the calcium ion concentration and so reduce the hardness. Mistake #1: Misinterpreting the key verb. Common Ion Effect. The common-ion effect can be understood by considering the following question: What happens to the solubility of AgCl when we dissolve this salt in a solution that is already 0.10 M NaCl?

Exam Prep Package at ₹2999 Only × Contact Us. Learn the errors HSC students are making and avoid them. The common ion effect suppresses the ionization of a weak acid by adding more of an ion that is a product of this equilibrium. Many of these GMOs are created using recombinant DNA technology.

What happens if a second compound is added that has no common ions? But, it is simply a question of calculating Ksp. 10:00 AM to 7:00 PM IST all days. Evaluate the effect of mutation, gene flow and genetic drift on the gene pool of populations. The common ion effect also plays a role in the regulation of buffers. Suggest reasons for this. Question 27 (b) Criteria . Researching future directions of the use of biotechnology. Don't miss this! Adding a common ion prevents the weak acid or weak base from ionizing as much as it would without the added common ion. ‘The application of reproductive technologies in plant and animal breeding limits genetic diversity.’ To what extent is this statement correct?
