Chemistry
A buffer solution was prepared by dissolving 4.00 grams ofsodium propanate (NaCH3CH2CO2, FM 96.06 g/mol) in a solutioncontaining 0.100 moles of propanoic acid (CH3CH2CO2H) and dilutingthe mixture to 1.00 L. pKa for propanoic acid is 4.874.
(a) To this solution was added 5.00mL of 1.00 M HCl. Calculatethe pH of the resulting solution.
(b) To this solution was added 5.00mL of 1.00 M NaOH. Calculatethe pH of the resulting solution.
