Volatile (evaporate easily) [1]

3

Ethanol is an alcohol.
One use of ethanol is in alcoholic drinks.
Give two other uses of ethanol. [2]

Fuel

4

What type of reaction produces ethanoic acid from ethanol?

oxidation

5

Solutions of ethanoic acid and hydrochloric acid with the same concentration have different pH values.
Explain why the solution of ethanoic acid has a higher pH than the solution of hydrochloric acid. [2]

ethanoic acid is a weak acid
because it partially ionises

7

What type of chemical is used as a catalyst in this reaction? [1]

acid

8

Esters are used in perfumes because they smell pleasant and are volatile.
What does volatile mean? [1]

evaporates easily / quickly

What is the name of the gas? [1]

Carbon dioxide

10

The student found that hydrochloric acid reacts faster than ethanoic acid with scale.
Explain why hydrochloric acid reacts faster than ethanoic acid. [2]

hydrochloric acid is a strong acid
which fully ionises
