CHM 102 Sblock elements Objective Question

Question

Which of the following statements correctly compares the reactivity and solubility of sulphates, hydrogen sulphates, and sulphites of Group 1 elements?
Options
A Sulphates and hydrogen sulphates are insoluble, while sulphites are very soluble.
B Sulphites are less reactive than sulphates and hydrogen sulphates.
C The sulphates and hydrogen sulphates are all soluble in water, and sulphites are more reactive than sulphates and hydrogen sulphates.
Correct Answer
D All three types of compounds are insoluble in water but highly reactive.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 23 states: 'The sulphates (SO₄) and hydrogen sulphates (HSO₄) are all soluble in water.' and 'The sulphites (SO₃) are more reactive than the sulphates and hydrogen sulphates'.

Hint

Check the descriptions of solubility and reactivity for each type of compound in the 'Sulphates, hydrogen sulphates and sulphites of group 1 elements' section on page 23.
