A solution of 0.12 M NaOH is used to titrate 50.0 mL 0.27 M HCI. Determine the concentration of NaCl in the resulting solution at the equivalence point. M NaCl Submit Answer

A 50.0-mL sample of a 0.100 M solution of NaCN is titrated by 0.200 M HCl. Kb for CN is 2.0 105. Calculate the pH of the solution: a prior to the start of the titration; b after the addition of 15.0 mL of 0.200 M HCl; c at the equivalence point; d after the addition of 30.0 mL of 0.200 M HCl.

Consider a 10.0% (by mass) solution of hypochlorous acid. Assume the density of the solution to be 1.00 g/mL. A 30.0-mL sample of the solution is titrated with 0.419 M KOH. Calculate the pH of the solution (a) before titration. (b) halfway to the equivalence point. (c) at the equivalence point.

Malonic acid (HO2CCH2CO2H) is a diprotic acid. In the titration of malonic acid w ith NaOH, stoichiometric points occur at pH = 3.9 and 8.8. A 25.00-mL sample of malonic acid of unknown concentration is titrated with 0.0984 M NaOH, requiring 31.50 mL of the NaOH solution to reach the phenolphthalein end point. Calculate the concentration of the initial malonic acid solution. (Sec Exercise 113.)

Review Constants I Penodic Table A beaker with 1.00x102 mL of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 7.40 mL of a 0.460 M HCI solution to the beaker. How much will the pH change? The pK, of acetic acid is 4.740. Express your answer numerically to two decimal places. Use a minus (-) sign if the pH has decreased. > View Available Hint(s) να ΑΣφ ApH = 4.09 Submit Previous Answers X Incorrect; Try Again; 3 attempts remaining
