(Ka of CH3CO2H = 1.8 10-5) Using phenolphthalein as an indicator, a measured mass of vinegar was titrated with a measured amount of standardized NaOH solution until the endpoint was reached. Want better grades, but cant afford to pay for Numerade. B. A buffer is prepared by combining 150 mL of 0.50 M NaOH and 250 mL of a 0.75 M weak acid, HA. What is the pH of a solution after the addition of 25.0 mL of NaOH? E. 1.6 10^2 g. 19. B. Indicator pKa A. The equivalence point for a weak acid titration occurs at low pH. A. AgCl Ag2CrO4 AgBr AgI a buffer with a pH of 7.21? I'm so thank you! E. 0.4517 M, 35. Sodium acetate is used to mitigate water damage to concrete by acting as a concrete sealant, while also being environmentally benign and cheaper than the commonly used epoxy alternative for sealing concrete against water permeation. 1.4 10-10 M E. 7.93, 48. What mass of solid NaCH3CO2 (molar mass = 82.0 g/mol) should be Consider the reaction Concentration where we can write the same number of words as recon, right? If Ag+ is added until AgBr(s) just begins to precipitate, what are the concentrations of Ag+ and I-? A. What is the molar solubility of Fe(OH)3(s) in a solution that is buffered at pH 2.50 at 25 C? Atomic Mass: 22.989770 Assume no volume change occurs upon addition of KCl. D. 1.5 10-5 This problem has been solved! Molar mass of NaCH3CO2 (H2O)3 is 136.0796 g/mol Get control of 2022! The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. Table-2: Quantitative Data A Equation for the reaction (Balanced) NaHCO3(s) + CH3COOH(aq) NaCH3CO2(aq) + H2O(l) + CO2(g) B Molar Mass of the NaHCO3 841.007 gimo Molar Mass of CO2 214.00 glmol D Mass of NaHCO3 used in reaction 2.09 E Expected mass of CO2 produced or theoretical yield (you must show your calculations for each reactant using the mole.
