Calculate pH of 0.025 M solution of potassium hydrogen phthalate (KHP). pK1= 2.95, pK2=5.41
Given that pK1 = 3.0 and pK2 = 8.0 for an amino acid X. Total concentration of amino acid X in solution is 10 mM. Calculate the concentrations of protonated form (P), dipolar form (Z) and de-protonated form (D) of amino acid X at pH 2, and 10.
Calculate the pH of a solution containing 0.1 mol of phosphoric acid per liter of solution at SATP knowing that the SATP values of pK1, pK2, and pK3 for H3PO4 are 2.1, 7.2, and 12.4, respectively. Show your work.
Calculate the net charge of arginine (pK1=2.17, pK2=9.04, pK3=12.48) at pH 6.0. In order to calculate the net charge you must first calculate the percent “charged” for each ionizable functional group in the chemical structure of arginine. Use four significant digits in your calculation of the net charge.
