Naturally this most abundant alkali metal is used in soaps glass and pretzels?

Naturally, the most abundant alkali metal is not used in soaps, glass, and pretzels. The most abundant alkali metal is sodium, and it is used in the production of various compounds such as sodium chloride (table salt), sodium hydroxide (lye), and sodium carbonate (soda ash). Sodium is not directly used in the production of soaps, glass, or pretzels.

Soaps are made from fats and oils that are reacted with an alkali, such as sodium hydroxide or potassium hydroxide. Glass is made from a mixture of silica sand, soda ash, and limestone that are melted together at high temperatures. Pretzels are made from a dough that is boiled in a solution of baking soda (sodium bicarbonate) and then baked.
