Lab Report 1 Experiment: Identification of an foreigner complete Acid using Titration, IR and C-13 NMR instauration/Theory The purpose of doing this essay was to determine what an unnamed complete 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 isolated organic pane was titrated with 0.1 grinder sodium hydroxide. By adding the NaOH to the un cognize red-hot, the pH grows. This is because NaOH is a very(prenominal) strong institution, substance it has a juicy pH. When the buns is added to the cutting, the vinegarishulent slowly increases in pH. Before the dwelling 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 compound that accepts protons and an acid is a compound that donates protons. A typical acid-base answer proceeds 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 flow 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 horizontal surfaces. An eq! uivalence baksheesh is the point in the reaction where some(prenominal) the acid and the base argon at equilibrium. For example, H2A is an acid with two hydrogen atoms. The first reaction would look analogous this: H2A + H20  H30+ + HA- This reaction shows that there 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: BestEssayCheap.com
