You have a peptide with the sequence HEEDRKYYLCG. You may assume that the side-chain pKa values from the textbook are correct for the peptide. You may further assume that, for any pH more than 2 pH units away from the pKa value, the group will be fully protonated or deprotonated. a) What is the charge on the peptide at pH 1? b) What is the charge on the peptide at pH 6? c) What is the charge on the peptide at pH 12.5?
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.
