Nota: 10, Correciones profesor: Everything is correct! Scientifically, how do you know buffer is broken? I would apply Hendersson - Hasselbag equation, then check pH, and then, calculate [H+] and with it calculate pH.
Nota: 9.10. Correcciones profesor: 1d I expect to write the chemical equation of what is happening to help you reasoning. 4a water participates in this equilibrium as reagent. You have stated below! Be consistent!
Nota: 8.00. Correciones profesor: Q1: you forgot to mention safety reasons Q2: you did not refer to Raoult law Q3: acetone is not basic. it is neutral. The answer to the behavior is: you cannot separate by distillation two compounds with bp closer than 5
Nota: 9.30 Correcciones profesor: Q3. in the organic phase box, you cannot have benzoic acid unless something wrong happen, or if so, in a very little amount, in the suspension box, the solute is NaCl
Nota: 9.90. Correciones profesor: Q3. Question is perfectly done, but you have not taken into account the uncertainties of the question. You have 10.0 +/- 0.2 mL and 1.01+/- 0.02 g. Therefore, your result cannot be presented with 3 significant figures af
