Amino acids with an additional COOH group in the side chain are called acidic amino acids.
A 25.00 mL sample of a sodium hypoclorite liquid bleach is placed in a 250 mL volumetric flask and diluted to the mark. A 25.00 mL aliquot of this solution is placed in a 250 mL Erlenmeyer flask.
Solid copper (II) hydroxide from copper nitrate. First, add 30 mL of 3.0M sodium hydroxide to the solution in the Erlenmeyer Flask.Take a stirring rod and place the end about 1 cm into the solution; then tough the end to a 2 cm piece of red litmus..
Consider the titration of 50.0 mL of 0.217 M HN3 (Ka = 2.6 x 10-5) with 0.183 M NaOH. Calculate the pH of the solution after the addition of 29.6 mL of NaOH solution.
