MTM-Final Exam Basic Science Ionized forms like A- and BH+ are ________ and ______ diffusible across membrane water; poorly generic equation used to calculate week acidic and basic drugs 10 ^(pka-pH) = protonated/unprotonated equation to calculate weak acidic drugs 10^(pka-pH) = [nonionized(HA)]/[ionized(A-)] equation to calculate weak basic drugs 10^(pka-pH) = [ionized (BH+)]/[nonionized(B0] if the pka and pH difference is 1 or -1: ionization is 90% or 10% if the pka and pH differe...

ACS BIOCHEMISTRY EXAM QUESTION WITH COMPLETE SOLUTIONS LATEST 2023/2024 COMPLETE SOLUTIONS LATEST 2023/2024 Henderson-Hasselbach Equation - ANSWER pH = pKa + log ([A-] / [HA]) FMOC Chemical Synthesis - ANSWER Use d in synthesis of a growing amino acid chain to a polystyrene bead. FMOC is used as a protecting group on the N-terminus. Salting Out (Purification) - ANSWER Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solu...

If the pka of a weak acid is 2.5, at which pH will this drug become more ionized? A. pH 5 B. pH 2.5 C. pH 1.5 D. pH 1 correct answer: A. For a weak acid, a higher pH increases ionization Which equation describes the rate of drug dissolution from a tablet? A. Fick's Law B. Henderson-Hasselbalch equation C. Michaelis-Menten equation D. Noyes-Whitney equation correct answer: D. The Noyes-Whitney equation describes the rate of drug dissolution from a tablet. Fick's first law of di...

Typical Van der Waals energies are about: correct answers 2-4 kJ/mol A possible drug to treat COVID-19 has been discovered and is known to be a weak acid. At the pH of blood (7.4) the concentrations of acid and conjugate base are 0.075 and 0.025 respectively. What is its pKa? correct answers 3.00 What is the [A-]/[HA] ratio whent he weak acid is in solution alone pH unit above its pKa? correct answers 10:1 What are the primary chemical components present in a phosphate buffer at pH 7.4?...

ACS Biochemistry Practice Final FGCU 1. A weak acid, HA, has a pKa of 4.11. a) At pH 7.11, what will the ratio of conjugate base to acid be? (Henderson-Hasselbach equation: pH=pKa + log [A-]/[HA]) b) Based on answer to "a," is there more HA or A- at that pH? c) At pH 2.11, what will the ratio of conjugate base to acid be? d) Based on answer to "c," is there more HA or A- at that pH? e) At pH 4.11, what will the ratio of conjugate base to acid be? f) Fill in the blank: if pH is grea...

Acids and bases are usually demoted as strong or weak, what's the difference? - Answer-- Strong acids and bases - reaction with water is approximately 100% - Weak acids and bases - reaction with water is much less than 100% What does acid and base strength not dictate? - Answer-Acid or base strength is not a measure of concentration What are some examples of strong acids? - Answer-HNO3, HCl, H2SO4 and HClO4 are strong acids What are electrolytes and what's the connection to acids? - Ans...

Chem Exam 3 Things to Know 100% Verified Review Solution 2024/2025 Before starting a titration equation, what do we need to find? - ANS-Ka/Kb (given the other), volume, concentration of acid and base, initial mols of weak acid/base at the starting point of a titration, how do you find pH? - ANS-use a RICE table to find K expression equation, plug initial (not titrant) concentration into table and when you have K expression, solve for X. take -log of x for pH at the buffer region of a ti...
