Solubility and Strong Acids/Bases

Front

What is a strong base?

Back

A strong base is a substance that completely dissociates in water to produce hydroxide ions (OH-). Example: KOH (Potassium Hydroxide).

What defines a strong acid?

Back

A strong acid is one that completely ionizes in solution, releasing a high concentration of hydrogen ions (H+).

Front

What is the solubility rule for hydroxides?

Back

Most hydroxides are insoluble, except for those of alkali metals and some alkaline earth metals like Ca(OH)2, Sr(OH)2, and Ba(OH)2 which are soluble.
