Caesium hydroxide is a strong base (pK a = 15.76) containing the highly reactive alkali metal caesium, much like the other alkali metal hydroxides such as sodium hydroxide and potassium hydroxide. It is the strongest of the five alkali metal hydroxides. [ 7 ]
The pH of a basic solution at standard conditions is greater than seven. Bases are bitter. [5] ... Cesium hydroxide: CsOH Magnesium hydroxide: Mg(OH) 2: Calcium ...

A vigorous reaction occurs, producing hydrogen gas and the specific alkali hydroxide. For example, if sodium is the alkali metal: 2 Na + 2 H 2 O → 2 NaOH + H 2. Sodium hydroxide is an important industrial chemical, where it is produced by the chloralkali process.
Caesium carbonate can be prepared by thermal decomposition of caesium oxalate. [3] Upon heating, caesium oxalate is converted to caesium carbonate with emission of carbon monoxide. Cs 2 C 2 O 4 → Cs 2 CO 3 + CO. It can also be synthesized by reacting caesium hydroxide with carbon dioxide. [3] 2 CsOH + CO 2 → Cs 2 CO 3 + H 2 O
Calcined gypsum is an alternative material in industrial plasters and mortars. Cement, cement kiln dust, fly ash, and lime kiln dust are potential substitutes for some construction uses of lime. Magnesium hydroxide is a substitute for lime in pH control, and magnesium oxide is a substitute for dolomitic lime as a flux in steelmaking. [28]
A strong acid, such as hydrochloric acid, at concentration 1 mol dm −3 has a pH of 0, while a strong alkali like sodium hydroxide, at the same concentration, has a pH of 14. Since pH is a logarithmic scale, a difference of one in pH is equivalent to a tenfold difference in hydrogen ion concentration.
A universal indicator is a pH indicator made of a solution of several compounds that exhibit various smooth colour changes over a wide range pH values to indicate the acidity or alkalinity of solutions. A universal indicator can be in paper form or present in a form of a solution.It doesn't contain a pH itself. [1]
