Create a schematic diagram on how to prepare a Phosphate Buffer NaH2PO4 - K2HPO4 with a final volume of 500. mL, concentration of 0.10M with a pH of 7.20 from 0.20 M NaH2PO4 and solid K2HPO4. Note: Ka = 6.3 x 10-8 Reminders: Show all calculations before preparing the schematic diagram. 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
