Acetic acid ( CH 3 COOH , K a = 5.62 × 10 − 5 ) is a weak acid, so the salt sodium acetate ( CH 3 COONa ) acts as a weak base. Calculate the pH of a 0.772 M solution of sodium acetate.
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...

please explain in clear writing. Acetic acid (CH3COOH) is made industrially by the reaction of methanol and carbon monoxide: CH3OH(1) + CO(g) + CH3COOH() ArH=-355.9 kJ mol-1 If you produce 1.00 L of acetic acid (density = 1.044 g mL-1) by this reaction, what quantity of heat is evolved?
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)...

6.82. Acetic acid, CH, COOH, is contained in vinegar. Suppose acetic acid was formed from its elements, according to the following equation: 2C(graphite) + 2H2(g) + O2(g) → CH,COOH(1) Find the enthalpy change, AH, for this reaction, using the following data: CH, COOH(D) +20 (9) ► 2007 (9) + 2H2O(); AH = -874 kJ C(graphite) + O2(g) + CO2(g); AH = -394 kJ H2(g) + O2(g) → H2O(l); AH = -286 kJ
