enumerate the steps necessary to create a Phosphate Buffer NaH2PO4 - K2HPO4 with a final volume of 500 mL, a concentration of 0.10M, and a pH of 7.20 using 0.20 M NaH2PO4 and solid K2HPO4. Nota bene: Ka equals 6.3 x 10-8. (show computation as well) For solid K2HPO4, calculate for the mass (based from calculated moles of salt) rather than the volume since this is a solid substance.
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.
