Question 1
1.
Which two of the following substances dissolve in water to form alkaline solutions?
Aluminium hydroxide
Ammonia
Copper hydroxide
Iron hydroxide
Sodium hydroxide
Question 2
2.
This question is about sodium hydroxide and sulphuric acid and the reaction between them. Which two of the statements are correct?
Hydrogen ions make the sodium hydroxide solution alkaline
Sodium hydroxide and sulphuric acid react to produce a base
Sodium hydroxide and sulphuric acid react to produce the salt, sodium sulphate
Sodium hydroxide solution is alkaline because it contains OH⁻ (aq) ions
Sulphuric acid solution contains H
-
(aq) ions
