Question:medium

Identify the correct statements from the following
I. LiF is less soluble in water than NaF
II. Both LiCl and MgCl\(_2\) are insoluble in ethanol
III. Both Li and Mg form nitrides
IV. Na\(_2\)CO\(_3\) gives CO\(_2\) on heating

Show Hint

The diagonal relationship between Lithium (Group 1, Period 2) and Magnesium (Group 2, Period 3) is a key concept. They share many similar properties, such as forming nitrides, having covalent halides soluble in organic solvents, and having carbonates that decompose on heating.
