Caesium Hydroxide[edit]

Caesium hydroxide is an inorganic compound with the formula CsOH. It is a strong base and is highly reactive. It is the hydroxide of the alkali metal caesium, and it is notable for being one of the strongest bases known.

Properties[edit]

Caesium hydroxide is a white solid that is highly soluble in water. It is hygroscopic, meaning it readily absorbs moisture from the air. When dissolved in water, it forms a strongly alkaline solution. The compound is known for its ability to corrode glass, which is a property shared with other strong bases like sodium hydroxide and potassium hydroxide.

Preparation[edit]

Caesium hydroxide can be prepared by the reaction of caesium metal with water:

$2 Cs + {2 H}_{2} O \to 2 CsOH + H_{2} ↑$

This reaction is highly exothermic and produces hydrogen gas. Alternatively, caesium hydroxide can be produced by the reaction of caesium carbonate with a strong acid, followed by evaporation of the water:

${Cs}_{2} {CO}_{3} + 2 HCl \to 2 CsCl + H_{2} O + {CO}_{2} ↑$

Applications[edit]

Caesium hydroxide is used in a variety of applications, primarily in the field of organic synthesis. It serves as a strong base in chemical reactions and is used in the production of other caesium compounds. Due to its ability to absorb moisture, it is also used as a desiccant in certain industrial processes.

Safety[edit]

Caesium hydroxide is highly corrosive and can cause severe burns upon contact with skin. It is important to handle it with appropriate safety precautions, including the use of gloves and eye protection. In case of contact with skin or eyes, it should be washed off immediately with plenty of water.
