SAP-9.B.2 When dissolved in solution, strong bases (e.g., group I and II hydroxides) completely dissociate to produce hydroxide ions. It is given that the concentration of NaOH solution is 0.10 M. ions is 0.010 M. Let us illustrate this with the following example. Potent inhaled anesthetics degrade in the presence of the strong bases (sodium hydroxide or potassium hydroxide) in carbon dioxide (CO2) absorbents. A strong Arrhenius base, like a strong acid, is a compound that ionizes completely or near-completely in solution. pOH can be used to calculate the concentration of hydroxide ions in solutions of strong Arrhenius bases: [OH-] = 10-pOH where [OH-] is the concentration of hydroxide ions in mol L-1 (mol/L or M).

Some common strong Arrhenius bases include: Potassium hydroxide (KOH) Sodium hydroxide (NaOH) Barium hydroxide (Ba(OH) 2) Caesium hydroxide (CsOH) Strontium hydroxide (Sr(OH) 2) Calcium hydroxide (Ca(OH) 2) Lithium hydroxide (LiOH) Rubidium hydroxide (RbOH) The cations of these strong bases appear in the first and second groups of the periodic table (alkali and earth alkali metals). It is used as a source of barium to produce other barium salts as barium phosphate, barium sulfide and barium sulfate that are using in the chemical industry in diverse processes. Barium hydroxide is a strong base as it dissociates itself completely in water and gives out BaO cation and Hydroxide cation. NH3 (ammonia) weak base. Ca(OH)2 is a strong base.

Strontium hydroxide - Sr (OH) 2. As such, the concentration of OH-in strong base solution is equal to the initial concentration of the strong base, and thus the pOH (and pH) of the strong base solution is easily calculated. It is used as a strong base in organic chemistry. An acid or a base is weak when it is partially ionized in aqueous solution, that is, non-ionized ions and molecules are found in the solution.
