Li and Mg both form chlorides which are:
Unstable
Highly ionic
Alkaline
Deliquescent
Both LiCl and MgCl2 are deliquescent as they readily dissolve in water which they absorb.
Rationalise the given statements and give chemical reactions:
• Lead(II) chloride reacts with Cl2 to give PbCl4.
• Lead(IV) chloride is highly unstable towards heat.
• Lead is known not to form an iodide, PbI4.
