Ionic Equilibrium

Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.

Arrhenius Acid

Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.

Bronsted Lowry Base In Inorganic Chemistry

Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.

Calcium Benzoate: a) A sample of saturated CaBz2 solution is at equilibrium. The initially-prepared concentrations are [Ca?+]; = A and [Bz]; =B. This sample is allowed to saturate, and then the remaining solid is filtered out. As determined by titration, the final benzoate ion concentration in solution is [Bz]:= C. What is the solubility product of CaBz2, in terms of A, B, and C?| b) In our lab experiment, the CaBz2 solution is saturated at equilibrium before titration. Why must the CaBz2 solutions be saturated?

Zn²+ and Mn²+ (starting concentration 102 mol/L) should be separated by fractionated precipitation using H₂S. Does a pH or pH range exist allowing to completely precipitate one metal (i.e. the remaining concentration of the precipitated ion has to be 105 mol/L or less) whereas the other stays in solution at its initial concentration? Please calculate this pH range!
