1. CHES buffer is a commonly used buffer system in biochemistry and molecular biology. The reagent of CHES is N-cyclohexyl-2-aminoethanesulfonic acid, a monoprotic acid, with a formula of CSH17NO.S. It has a useful pH range between 8.6 to 10. It is made by reacting with NaOH in situ. How many grams of solid CHES should be added to 100.0 mL of 0.500 M NAOH to make a buffer of pH = 9.54? Ka for CHES is 5.0 x 100 Please note NaOH is used to make the CHES salt, and not part of HH equation.
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.
