A chemistry graduate student is given 250. mL of a 1.50M hydrocyanic acid (HCN) solution. Hydrocyanic acid is a weak acid with K,=4.9 × 10 1º. What mass of NaCN should the student dissolve in the HCN solution to turn it into a buffer with pH = 8.84? You may assume that the volume of the solution doesn't change when the NaCN is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. ?
3a) A student determines the concentration of a sodium hydroxide solution by titration with standardized KHP. S/he obtains the values: 0.190 M, 0.202 M, and 0.205 M. Should the value 0.190 M be rejected? Apply the Q Test. For three values Q must be greater than 0.94 to reject the number. Q = suspect nearest | largest - - smallest b) The student de to repeat the experiment two more The five values now include: 0.190 M, 0.202 M, 0.205 M, 0.201M and 0.203M. Use the Q Test to see if the first value may be rejected. For five values Q must be greater than 0.64 to reject the number. c) Solve for the average Molarity of the measurements from part b with and without the rejected number. Is there value in repeating an experiment several times?
Question 1 1 Consider a flask containing 25.00 mL of 0.100 M sodium benzoate (NaCgH5CO0). This is titrated with a 0.110 M nitric acid solution from a burette. Given: Kp of C,H5CO00" is 1.6 × 10-10. 1.1 Determine the pH of the solution in the flask after 32.00 mL of the acid has been added? You must show any reaction equation(s) that you may think are necessary. 1.2 Determine the pH of the solution in the flask at the half-way point of the titration.
