Titration Lab Report Discussion

1. To titrate a hydrochloric acid solution of “unknown” concentration with standardized 0.5M sodium hydroxide.

In class, we performed a titration lab in order to determine the amount of potassium permanganate needed to titrate 1.0 g/mL of hydrogen peroxide. My team found that 42 drops of KMnO4 was needed to titrate the hydrogen peroxide solution. To find this, we first must find the amount of each reactant is in 1.0 g. To get 1 gram, 30 drops of H2O2 was needed while KMnO4 required 32 drops. In order to dilute the hydrogen peroxide, we added 2.02 g of H2O2 and 48.08 g of distilled water to get a 50.10 g solution. The next step was to find the new molarity of the peroxide.

Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralisation, which is often indicated by a colour change. The solution called the titrant must satisfy the necessary requirements to be a primary or secondary standard. In a broad sense, titration is a technique to determine the concentration of an unknown solution. We can use the reaction to find out the molarity of the solution by measuring the product(s) that is formed.

It should be noted that not all supplies are listed here as exactly what is needed to perform each method but a complete list can be found in the lab manual preceding each experiment.

In the titration, I used these available instruments to ensure my results would be as accurate as possible.

ii. The second part of the titration series involves titration of NaOH with Hydrochloric acid (HCL). Again, three reps of titration and a blank titration have to be completed. A volumetric pipet is used to measure 10.00mL of HCL into three labeled conical flasks. Then the flasks are filled with deionized water until about the 50mL mark. A buret is

During a titration the pH of the solution will be monitored using a pH meter from that we get a titration curve. The titration curve is then used to determine the equivalent molecular weight and Ka value of the unknown weak acid, from that we are

In a lab, when one performs a titration it is mainly performed few times, but the same procedure is carried out also in industry but in large quantities and not just few titrations but many. The procedure is mainly the same but in industry one needs to find a balance between precision and speed, one way to reduce time-wasting is that when preparing a standard solution instead of using a burette, one weighs the liquids so as to quicken the process. One may also find automatic titrations apparatus in more advance labs which prepares both the standard solution as well as performs the titrations with accurate results. Also in industry to further increase the speed and also the accuracy, when preparing standard solutions, one may use a Gilson Pipette which works by setting the amount of volume which needs to be extracted from the solution and by pressing a lever, the exact volume is taken and transferred. This technique takes the use of the bulb pipette, because it’s easier to use and more precise when working with small

Before starting the titration it is important to condition the buret two or three times with titrant solution. We will also need to check the tip of the buret to make sure that it is free from air bubble. If an air bubble is present during the titration, the volume readings will be in error. Also make sure that you read the volume of titrant added keeping your eyes at the level of the meniscus of the solution. Reading from an angle will result in another source of error.

For this experiment, titrations on a weak acid, acetic acid, and a buffer were performed. Acetic acid was titrated with NaOH in order to observe the half-equivalence point as well as the equivalence point. Then, the buffer and the buffered acetic acid solution prepared faced additional titration with NaOH and HCl to evaluate the differing buffering effects following the addition of a strong acid and strong base. Finally, the buffer’s buffering capacity was calculated. If the experiment were to be repeated, it would be interesting to observe the buffering effects following a titration between a weak base and a buffer instead with greater concentrations. The change in the concentration following the preparation of buffer with a weak base and its conjugate acid would pose for an interesting experiment to observe an increase in the buffering capacity.

Titration is a technique that is used to determine and analyze the concentration of a substance. It is based off of mole ratios between the two substances taking part in the lab. Burets are used in the titration of substances, which are large glass tubes with a valve attached to the bottom to allow the specially measured amount of substance into another. The amount of each substance must be very precise and be recorded properly. The analysis of these reactions are usually simplified to a 1:1 ratio, just as this lab was.

The method of titration was discovered in late 1800’s by a french pioneer name Francois Antoine Henri Descroizilles. Titration is a process used to find concentration of an unknown compound. This process is used in labs to find information need in everyday life.For instance, titration is used during blood test and urine test to determine the concentration

An acid-base titration is the determination of the concentration of an acid or base by exactly neutralizing the acid/base with an acid or base of known concentration. This allows for quantitative analysis of the concentration of an unknown acid

For generating valuable data with a desired accuracy and to quantify concentration of the constituents present in the samples being analyzed.
