The pH of a hypoiodous acid/sodium hypoiodite buffer in which the concentration of the weak acid component is 0.280 M and the concentration of the conjugate base is 0.110 M is 10.23. Suppose 0.733 g of solid NaOH are added to 100 mL of this buffer solution. What is the pH after the addition? Clickhere for the table of Ionization Constants of Weak Acids.
Rapid glycolysis during strenuous exercise supplies the ATP needed for muscle contraction. Ever since the lactate dehydrogenase reaction does not produce any ATP, would glycolysis be more proficient if this reaction did not occur, and pyruvate was..
