Industrial Chemistry

Question 1

Redox titration

Answer 1

Using a redox reaction (rather than, e.g., a neutralisation reaction) to determine the concentration of a solution.

Question 2

Primary standard

Answer 2

Solution with accurately
know concentration. Prepared by
dissolving a measured amount of solute in a known
volume of solvent.

Question 3

Equilibrium

Answer 3

Refers to the situation when the forward reaction has the same rate as the backward reaction when we have a reversible reaction. Note that this does NOT mean “nothing is happening”, both reactions ARE occurring.

Question 4

Haber process

Answer 4

Method of producing ammonia from hydrogen and nitrogen.

Question 5

Conditions required for Haber process

Answer 5

Temperature of 450 degrees centigrade, pressure of 200 atmospheres, iron catalyst.

Question 6

Importance of Haber process

Answer 6

Produces ammonia which is required to make fertilizers which are essential to intensive food production.
