Question

Which statement accurately describes the reaction of Group 1 metals with water and the solubility of their hydroxides?
Options
A All Group 1 metals react slowly with water to produce metal oxides and hydrogen gas.
B Lithium reacts violently with water, while other Group 1 metals react slowly.
C With the exception of lithium, Group 1 metals react violently with water to give hydroxides and hydrogen gas, and their hydroxides are very soluble.
Correct Answer
D All Group 1 metals react violently, and all their hydroxides, including LiOH, are very soluble in water.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 10 states: 'With the exception of lithium which reacts slowly, group 1 metals react violently with water to give the corresponding hydroxide and liberate hydrogen gas.' It also mentions: 'The hydroxides of group 1 metals are strong bases and are very soluble in water.' and specifically, 'Lithium hydroxide (LiOH) is slightly soluble in water.' Option C correctly captures these details.

Hint

Focus on the reactivity trend with water and the solubility of LiOH versus other Group 1 hydroxides, as explained on page 10.
