A 20.9 mL sample of 0.306 M trimethylamine, (CH3)3N, is titrated with 0.304 M nitric acid. The pH before the addition of any nitric acid is . Use the Tables link in the References for any equilibrium constants that are required.
A 25.0 mL sample of a 0.2300 M solution of aqueous trimethylamine is titrated with a 0.2875 M solution of HCl. Calculate the pH of the solution after 10.0, 20.0, and 30.0 mL of acid have been added; pKb of (CH3)3N = 4.19 at 25°C.
A 25.0 mL sample of a 0.340 M solution of aqueous trimethylamine is titrated with a 0.425 m solution of HCl. Calculate the pH of the solution after 10.0, 20.0, and 30.0 mL of acid have been added; pKb of (CH3)3N=4.19 at 25 C.
