A 100 mL solution of 0.1 M amino acid (AA) at pH 1.0 was titrated with NAOH solution. The pH was monitored, and the results were plotted on a graph, as shown below. The key points in the titration are designated I to VII. 14 12 VII 10 VI V IV 8 pH 6 III 4 2 II 0.5 1 1.5 2 2.5 3 Equivalents of OH a. What is the possible identity of the amino acid? (Choices: lysine, proline, aspartic acid, alanine) b. What is the isoelectric point of AA? (Choices: I, II, III, IV, V, VI, VII, VIII, IX, X)
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.
