Calcium Hydroxide



 This is the chemical structure of calcium hydroxide. Todd Helmenstine

Calcium hydroxide: Ca(OH)2

Calcium hydroxide is considered a strong to medium strength base. It will completely dissociate in solutions of less than 0.01 M, but weakens as concentration increases.

Calcium hydroxide is also known as calcium dihydroxide, calcium hydrate, hydralime, hydrated lime, caustic lime, slaked lime, lime hydrate, lime water and milk of lime. The chemical is white or colorless and may be crystalline.

Pyridine



 This is the chemical structure of pyridine. Todd Helmenstine

Pyridine: C5H5N

Pyridine is a weak Lewis base. It is also known as azabenzene. Pyridine is a highly flammable, colorless liquid. It's soluble in water and has a distinctive fishy smell that most people find repugnant and possibly nauseating. One interesting pyridine fact is that the chemical is commonly added as a denaturant to ethanol to make it unsuitable for drinking.

Sodium Hydroxide



 This is the chemical structure of sodium hydroxide. Todd Helmenstine

Sodium hydroxide: NaOH

Sodium hydroxide is a strong base. It is also known as lye, caustic soda, soda lye, white caustic, natrium causticum and sodium hydrate. Sodium hydroxide is an extremely caustic white solid. It's used for many processes, including soap-making, as a drain cleaner, to make other chemicals, and to increase the alkalinity of solutions.


Zinc Hydroxide


 This is the chemical structure of zinc hydroxide. Todd Helmenstine

Zinc hydroxide: Zn(OH)2

Zinc hydroxide is a weak base. Zinc hydroxide is a white solid. It occurs naturally or is prepared in a lab. It's easily prepared by adding sodium hydroxide to any zinc salt solution.
