5. Use the mass of the acid, the concentration of NaOH and the volume of NaOH added at the first equivalence point to calculate the molar mass of the acid: (Show your work clearly and include proper units.) Calculated Molar mass of the unknown acid= Label the areas of the curve where a buffer is present. Locate the point where pH=pKa (halfway to the equivalence point.) Label pK, on the graph. If the acid is polyprotic, label the pK, for each equivalence point on the graph.
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.
