1

What does a solution consist of?

A salute dissolved in a solvent

2

If there is a lot of solute in a solution, is the concentration high or low?

High

3

If there is not a lot of solute in a solution, is the concentration high or low?

Low

4

What is a dilute acid?

An acid which has a low ratio of acid to volume of solution

5

What is a concentrated acid?

An acid with a high ratio of acid to volume of solution

6

What is a strong acid?

An acid where all of its molecules release H+ ions (fully ionised)

7

What is a weak acid?

An acid where only a partial amount of their molecules release H+ ions (partially ionised)

8

Give an example of a weak acid.

Ethanoic acid

9

Give an example of a strong acid.

Nitric acid

10

In an aqueous solution, what happens to the pH if the concentration increases by a factor of 10?

It decreases by 1

11

At the same concentration, does a strong acid or a weak acid have a lower pH?

Strong acid

12

What graph shows the effect on pH changing compared to the volume of solution?

The pH titration curve
