4. Categorize the aqueous solutions of the following salts as acidic, basic or neutral. Explain your answers based on the pH nature of the ions. Salt Solution pH Nature of Solution Cation Formula Anion Formula (includes its charge) & pH (includes its charge) & pH nature nature Cesium nitrite Zinc chloride Barium hydrogen sulfate Ammonium bromide Strontium perchlorate
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.
Note : Strong acids and strong bases giveaway neutral cations and neutral anions respectively.
Cesium nitrate
cation formula - Cs+
pH nature - basic
anion formula - NO3-
pH nature acidic
pH nature of the solution - weakly acidic (since it salt of weak acid nitrous acid)
Zinc Chloride
cation formula - Zn2+
pH nature - acidic
anion formula - Cl-
pH nature - acidic
pH nature of the solution - Slightly acidic (since it is formed from weak base Zn(OH)2 and strong acid HCl)
