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.

What is the concentration and expected pH of a buffer created by mixing 6.89 g of Na2HPO4 (FM
141.96) with 9.18 g of NaH2PO4 (FM 119.98) and diluting to a final volume of 500.0 mL?
Starting with 1.00 M NaOH and solid NaH2PO4 (FM 119.98), you want to make 500.0 mL of a 0.250 M
buffer at pH 12.00. How much solid do you use, and what volume of NaOH would you expect to add?
