IBDP Chemistry Question Analysis Topic: Chemistry - Short Questions
Exam Questions:
1) Define the following terms:
(i) Molar conductivity (⋀m)
(ii) Secondary batteries
2) (i) Give two examples of macromolecules that are chosen as drug targets.
(ii) What are antiseptic? Give an example.
(iii) Why is use of aspartame limited to cold foods and soft drinks?
Answers:
For IBDP Chemistry, you should know:
1) (i) Molar conductivity
The efficiency with which a given electrolyte conducts electricity in solution is measured by molar conductivity, which is defined as the conductivity of an electrolyte solution divided by the molar concentration of the electrolyte.
It is the power of conductivity of all the ions produced by dissolving one electrolyte mole in a solution.
(ii) Secondary batteries
A form of electrical battery known as a rechargeable battery, storage battery, secondary cell, or accumulator can be charged, discharged, and then charged repeatedly. This is opposed to a non-rechargeable or primary battery, which is delivered fully charged and discarded once used up.
2) (i) The macromolecules chosen as drug targets are enzymes and receptors.
(ii) Living tissues, such as wounds, cuts, and diseased skin surfaces, are treated with antiseptics.
Furacine and soframicine are two examples.
(iii) The most useful artificial sweetener is aspartame. Since it becomes unstable at cooking temperatures, its usage is restricted to cold foods and soft drinks.
