In the series of alkalis LiOH – NaOH – KOH – RbOH – CsOH, their strength and solubility in water: increases.
The strongest alkali in this series is CsOH. Since the strength of alkalis and their solubility in water, respectively, increases with increasing radius of the cation (the cation in our case is Cs, of course). And the radius of the cation increases “from top to bottom” when we look at the periodic system of Mendeleev.
Therefore, the reaction of CsOH with the same water will be accompanied by significant heat release.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
