Strong Electrolytes : Essentially all ionic compounds and the strong acids. This is the example of a strong acid and a weak base. That is, while element masses differ, when it comes to bonding with other atoms, the number of atoms, expressed in moles, is the determining factor in how much of a given element or compound will react with a given mass of another. H 2 SO 4 + CaCl 2 CaSO4 + HCl d. is an acid reacting with a metal to liberate hydrogen. To actually apply this method would depend on whether the base is soluble (i. General Anhydrite Information : Chemical Formula: CaSO4 : Composition: Molecular Weight = 136. Because of salt hydrolysis, the pH of a weak acid + strong base is in the basic range due to the anion of the salt hydrolyzing water to produce hydroxide. Thus, a buffer solution contains both an acid species and a base species in equilibrium. Aqueous solution of Calcium Sulphate is neutral as it does not undergo cation or anion hydrolysis to yield acidic or basic solution It is a salt of a strong acid (H2SO4) and strong base (Ca (OH)2).
