- A chemistry graduate student is given 500.mL of a 0.80M chloroacetic acid (HCH2ClCO2) solution. Chloroacetic acid is a weak acid with Ka = 1.3x10^−3. What mass of NaCH2ClCO2 should the student dissolve in the HCH2ClCO2 solution to turn it into a buffer with pH = 3.08 ?You may assume that the volume of the solution doesn't change when the NaCH2ClCO2 is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.arrow_forwardIn a titration, the equivalence point is the moment at which the number of moles of H+ from the acid that has been added is equal to the number of moles of OH- from the base that has been added. Remember that in a molecule like H2SO4, there are 2 moles of H+ per mole of H2SO4. 16.31 mL of 0.100M H2SO4(aq) is placed in a beaker. After 17.98 mL of NaOH is added to the beaker, the equivalence point is reached.

- Determine the mass of solid NaCH₃COO that must be dissolved in an existing 500.0 mL solution of 0.200 M CH₃COOH to form a buffer with a pH equal to 5.00. The value of Ka for CH₃COOH is 1.8 × 10⁻⁵. I've seen a few similar problems solved on here, but mine is asking me to set up an ICE table and then solve for Ka, and I don't understand why I'm supposed to do that.arrow_forwarda buffer has been prepared using 0.1 moles of sodium acetate (NaAc) and 0.1 moles of acetic acid (HAc), which has been added to 100 ml of water.
