Determining the Concentration of Limewater Solution * Download the original word document * Save this to your mycoursework page * View the word count and other details * Learn about Plagiarism Determining the Concentration of Limewater Solution Aim The aim of this experiment is to find the concentration of 250 cm3 of limewater solution, which has been made such that it contains approximately 1g dm-3 of calcium hydroxide. I am required to design my own experiment and choose a range of appropriate equipment and apparatus. The indicator will be supplied to me. Also available is hydrochloric acid which has a concentration of exactly 2.00 mol dm-3, this concentration is too much though so it is necessary to dilute it.coeg egr seegegw oreg egk ineg foeg eg.

That is why I have chosen the pipette, volumetric flask and burette. All of these instruments have an accuracy of 0.05%cm3, which is suitable for my experiment and should produce accurate and reliable results. sofire, please do not redistribute this essay.

Anybody found doing so will be permanently banned. In making my choice of indicator I also had to be very careful. The Limewater used will be a relatively weak base so it will be appropriate to use methyl orange as it has an end point on the ph scale between 8-5. Whereas phenolphthalein indicator has an end point much higher up in the ph scale. So if I were to use the phenolphthalein indicator then the end point (colour change) ...read more.

    More concentrated solutions have more particles of reactant colliding between the water molecules which make the important collisions more likely. The lower the volume of the independent variable potassium iodide, the slower the reactions take place. Less concentrated solutions have fewer particles of reactant colliding between water molecules which make the important collisions less likely.

    Use this, the concentration of the titrant, and the stoichiometry of the titration reaction to calculate the number of moles of reactant in your analyte solution. At the end-point of the experiment, the volume of the acid times the molarity of its hydrogen ions will equal the volume of the base times the molarity of its hydroxide ions.

    Error Analysis An error analysis is done on all the equipment that is used. This shows the percentage error in a reading. The higher the percentage error the less accurate the results. The burette has an error analysis of �0.05cm�.

    If done carefully, this can lead to relatively accurate measurements of the unknown concentration. Apparatus & Materials: * NaOH solution * HCL solution (1.00 x 10��M) or H2SO4 solution (1.00 x 10��M) * Phenolphthalein solution * Beaker (500cm�) * Burette(50cm�)

    Hydrochloric acid also reacts very strongly with certain metals such as calcium and must not be kept or stored any where near them. Due to these factors, goggles must be worn at all times. It is also advisable to wear a lab coat and latex gloves.

    Use the same amount of methyl orange (indicator). 3. Use acid from the same stock as it is mixed by the technicians and could be slightly different. 4. The temp in the room could affect the rates of reaction of the acid.

    (How Far? How Fast?) Once we have measured exactly how much reagent was used we can then go on to work out the concentration by using the volume value. The reaction I've been discussing above is a strong acid with a weak alkali.
