Volumetric Analysis: Acid-Base

Question 1

What is a solution?

3

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

What is the concentration of a solution?

Answer 2

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

Question 3

What is the morality of a solution?

Answer 3

The molarity of a solution is the number of moles of solute per liter of solution

Question 4

What is 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 does the number of moles equal.

Answer 5

Volume (in cm^3) x molarity divided by 1000

Question 6

What does the number of moles of solute in diluted solution equal?

Answer 6

The number of moles of solute in concentrated solution

Question 7

What is a standard solution?

Answer 7

A solution whose concentration is accurately known

Question 8

What is a primary standard?

3

Answer 8

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 9

What is a titration?

Answer 9

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
