For each of the following compounds, decide whether the compound's solubility in aqueous solution changes with pH. If the solubility does change, pick the pH at which you'd expect the highest solubility. You'll find K, data in the ALEKS Data tab. P compound CaCl₂ Ca, (PO4)₂ MgCl, Does solubility change with pH? yes no O yes O no yes O no pH = 7 highest solubility pH = 6 X pH = 4 S
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.


When one of the component ions is a weak acid or base, the solubility of the salt is affected by pH.
The salts which are acidic in nature are less soluble in acidic solutions and more soluble in solutions that has pH value greater than 7 (basic solution).
