Question 1

Define a solution

Answer 1

A solution is a completely perfect mixture of a solute and a solvent. In a solution the particles of the solute are uniformly distributed throughout the solvent, i.e. the mixture is homogeneous.

Question 2

Define concentration

Answer 2

The concentration of a solution is the amount of solute that is dissolved in a given volume of solution.

Question 3

Define molarity

Answer 3

The Molarity of a solution is the number of moles of solute per litre of solution

Question 4

Define a 1M (one molar) solution

Answer 4

A 1M (one molar) solution is one that contains one mole of the solute dissolved in one litre of solution

Question 5

What is the formula to find the number of moles?

Answer 5

1000

Question 6

Define a standard solution

Answer 6

A standard solution is a solution whose concentration is accurately known

Question 7

Define primary standard

Answer 7

A primary standard is a substance that can be obtained in a stable, pure and soluble solid form so that it can be weighed out and dissolved in water to give a solution of accurately known concentration.

Question 8

Define titration

Answer 8

A titration is a laboratory procedure where a measured volume of one solution is added to a known volume of another solution until the reaction is complete
