If the ka of an acid of 3.5
Web23 feb. 2024 · If you need to determine the pH of a solution from the pKa of the acid dissolved (which can be determined in turn from its acid dissociation constant Ka), you can use the Henderson-Hasselbach … Web4. To prepare a buffer containing CH3CO2H and NaCH3CO2 and having a pH of 5, the ratio of the concentration of CH3CO2H to that of NaCH3CO2 should be about 1/1 1.8/1 1/1.8 5.0/1. Lactic acid (CH3CHOHCO2H) is found in sour milk, in sauerkraut, and in muscles after activity. (Ka for lactic acid = 1.4 104.)

WebpKa is the negative log of the equilibrium constant Ka, so -log (Ka). So you'd need to calculate the Ka and you can do that by measuring the concentrations of your reactants and products at equilibrium and plug them into the equilibrium expression for the deprotonation of water. Hope that helps. ( 1 vote) wey.anderson27 Webp K a = − log K a. Acid dissociation constant is the equilibrium constant of the dissociation of ions of an acid in an aqueous solution.
