4. Mr. Burnes bought a bottle of vinegar and wondered how concentrated the acetic acid (CH-COOH; mm = 60.05 g/mol) was inside. He titrated it with 0.00182 M NaOH that he found in a general chemistry laboratory. It took 9.90 mL of NaOH to reach the equivalence point. See titration curve on next page. A. What is the concentration of acetic acid if 23.7 mL of vinegar was used for the titration? B. Mr. Burnes bought the economy size bottle...

10. (a) A chemist needed a buffered solution of propionic acid (CH,CH,COOH) and its salt (CH,CH,COON.). Calculate the ratio (CH:CH;COONA] / [CH;CH;COOH] required to yield a pH of 4.A0 (Ka for propionic acid = 1.3x10) (b) A buffer solution is prepared by mixing 1.AB5 grams of acetic acid (CH3COOH) and 3.01C grams of sodium acetate (CH3COONA) and making the total volume to one litre. Calculate the pH of the buffer solution. (Ka = 1.8x10°) (RAM of H=1, C=12, O=16, Na=23)...

2. Carly the chemistry student performs an experiment with vinegar (active ingredient acetic acid, CH,COOH) and baking soda (NaHCO3). Her professor asks her to place varying amounts of baking soda and vinegar into sealable plastic bags, quickly seal the bags, and observe the reaction. The balanced chemical equation for the reaction is given here NaHCO3(aq) + CH.COOH(aq) → CO2(g) + H20(1) - NaCH,COO(aq) a) Use limiting reagent calculations to fill in the following table. Please show your work Trial Baking...
