Compounds of Alkali Metals

The video tutorial explains the reactions of alkali metals with oxygen, forming oxides, peroxides, and superoxides. It discusses the stability and properties of these compounds, including their solubility in water and their behavior as strong bases. The tutorial also covers the formation and properties of alkali metal halides, highlighting their melting points and solubility trends. Additionally, it explores the reactions of alkali metals with oxoacids, emphasizing their electropositive nature and the formation of salts.

What do alkali metals form when they burn in air and oxygen?

Explain why lithium does not form superoxides.

How does the stability of peroxides and superoxides change as we move down the alkali metal group?

What happens to the solubility of alkali metal hydroxides as we move down the group?

Describe the reaction of alkali metal hydroxides with acids.

What is the trend in melting points of alkali metal halides as we move down the group?

Why is lithium carbonate less stable to heat compared to other alkali metal carbonates?
