Consider three hypothetical ionic solids: AX,AX2, and AX3 (each X forms X-). Each of these solids has the same Ksp value, 5.5 x10-7. You place 0.25 mol of each compound in a separate container and add enough water to bring the volume to 1.0 dm3 in each case. Write the chemical equation for each of the solids dissolving in water. Would you expect the concentration of each solution to be 0.25M in the compound? Explain, in some detail, why or why not. Would you expect the concentrations of the A cations (A+, A2+, and A3+) in the three solutions to be the same? Does just knowing the stoichiometry of each reaction help you determine the answer, or do you need something else? Explain your answer in detail, but without doing any arithmetic calculations. Of the three solids, which one would you expect to have the greatest molar solubility? Explain in detail, but without doing any arithmetic calculations. Calculate the molar solubility of each compound.

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.
