Lab Report 1 Experiment: Identification of an unacknowledged complete Acid using Titration, IR and C-13 NMR invention/Theory The purpose of doing this essay was to determine what an unnamed innate savage was by terminate a titration of it, doing an IR scan, and doing a C-13 NMR scan. By doing a titration, equilibrium was observed when the unknow organic pane was titrated with 0.1 grinder sodium hydroxide. By adding the NaOH to the unknown sulfurousulated, the pH grows. This is because NaOH is a very(prenominal) strong institution, convey it has a last pH. When the buns is added to the caustic, the biting slowly increases in pH. Before the ass was added to the solution, it was all acid. When the base was added to the acid, it mixed and raised the pH depending on how much was added. The response observed was an acid-base answer. The sodium hydroxide acted as a base, art object the unknown organic acid acted as an acid. A base is a com pound that accepts protons and an acid is a compound that donates protons. A typical acid-base reply bribe as the following: HA + H2O  H3O+ + A- In this reaction, HA is a generic acid and water is an amphoteric compound, meaning it can act as either an acid or base depending on what it is reacting with. In this case, water acts as a base, accepting the proton that acid HA donates.

A- is the left over is the desegregate base of the acid HA. H30+ is the conjugate acid of the base water. It is known that the unknown acid depute is a diprotic acid. A diprotic acid is an acid with ii comparability horiz ontal surfaces. An equivalence head teach! er is the point in the reaction where some(prenominal) the acid and the base ar at equilibrium. For example, H2A is an acid with two hydrogen atoms. The first reaction would look similar this: H2A + H20  H30+ + HA- This reaction shows that in that respect is another acid being formed afterwards the first reaction. This means that there is another equivalence point in the acid. That reaction looks like this: HA- + H20 ...If you want to get a full essay, order it on our website: OrderCustomPaper.com
