Webb30 dec. 2024 · Ca(OH) 2 is base, not an acid. Because it dissociates into OH – ions in an aqueous solution which quickly absorbs H + to form a water molecule. Ca(OH) 2 acts as Arrhenius base, According to the Arrhenius theory, the compound is said to be base when it produces OH – ion through ionization and increases the concentration of OH ... Webb9 apr. 2024 · Strong Acids: Generally, acids are substances with a pH value of less than 7.0. The value goes on decreasing as the amount of H+ ion increases in the solution. Strong acids are the substances that release H+ ions rapidly or that are 100% ionizable in the solution. Thus, the strong acids have less pH value, nearly 0 to 1.
