Hydrochloric Acid Titration
Introduction:
The aim of the experiment is to find the exact concentration of the hydrochloric acid (HCl) solution by reacting (titrating) it with the standard base sodium hydroxide (NaOH) solution.
Titration is the name of the analytical process that is used to determine the concentration of an unknown solution by reacting it with a standard solution (known concentration). The known concentration solution is called the titrant, and the unknown concentration solution is called the analyte.
The purpose of using HCl and NaOH is because they are strong acid and base, which means they will fully dissociate in water (will separate to ions). This is important because when the reaction reaches the equivalence point H and OH ions will combine together

Material:
To do this experiment some particular tools and instruments are needed. The Burette is used to put bace NaOH in it, it has an error of ± 0.1ml. In titration experiment the burette is hanged on holder above the Conical flask. The conical flask has the acid HCl in it, and it is the place where the acid react with the base. The Pipette is the instrument that used to measure the amount of the acid HCl before adding it to the conical flask, it’s error is ± 0.03ml. To put the base in the burette an instrument called Funnel is used. A wash bottle is used as well.
Procedure:
Before the instruments were used they were washed by deionized water. The reason behind cleaning the instruments with deionized water is to assure that they are clean and free of unwanted materials or previous samples that can interact with the samples used in the experiment and interrupt the measurements and results. The deionized water used because it has had all it’s minerals ions removed, and this is important for the aim of cleaning the instruments so no mineral ions will remain in the

1337 Words | 6 PagesStandard Sodium hydroxide solution is the alkaline solution that will be used to titrate with soda water as it is a common solution that can be easily found in an ordinary school laboratory. It is a strong base. Carbonic acid is a weak acid which will react with a strong base to form a basic (pH > 7) solution. When Phenolphthalein is added to Soda water, the resultant solution is colourless. After titration with a strong base (sodium hydroxide), the solution will turn to pink as the solution becomes

CaCO3, commonly referred to as limestone, is an organic substance and is, in a sense, the crystallised “carbonic salt” of the element, calcium2. In addition to being a salt, the pH level of Calcium Carbonate is 9.91, and it is therefore, a basic substance, due to the fact that it is comprised of a pH level higher than 7, which is neutral3. HCl, however, is the bodily acid found in the stomach of human beings.

The liquid was decanted and set aside for later use. After the tube was centrifuged, HCl was added along with deionized water. It was then heated in boiling water. The tube was heated because it allowed the insoluble solid to be broken down since it was

Buffer Lab Report
1344 Words | 6 PagesIntroduction Buffer is a solution that resists a change in pH when bases or acid are added. Solutions that are acidic contain high concentrations of hydrogen ions (H+) and have pH values less than seven. Buffer usually consist of a weak acid, and its conjugate base or a weak base and its conjugate acid. The function of buffer is to resist the changes in hydrogen ion concentration as a result of internal and environmental factor. This buffer experiment is important so that we relies the important of buffer in our life.

In back titration, excessive volumes of acid are always added. Of which, only a certain quantity would be neutralised. The number of moles of acid is eventually derived from titrating this excess acid with a strong base and using mole fractions to calculate. The quantity of acid neutralised is obtained by subtracting the moles of acid given at the start of the experiment, with the moles of acid titrated.

The drops were caused because the burette was not tightened enough at the bottom to avoid it from being hard to release the basic solution for titrating the acid. The volume of the acid used for each titration was 25ml. The volume of the solution was then calculated by subtracting the initial volume from the final volume. We then calculated the average volume at each temperature.
