The quality of water depends on several factors including oxygen-demanding wastes, disease-causing pathogens, microorganisms affecting health, plant nutrients, suspended solids and dissolved minerals. Other pollutants may be excess acidity due to acid rain, thermal pollution and substances such as benzene, chromium and mercury that are all toxic to aquatic life. As humans and land animals […]
Aim The purpose of this experiment is to determine the percentage by mass of calcium carbonate in eggshells. Introduction To avoid the breakage of eggs before reaching market, the eggshells needs to be as strong as possible. The strength of eggshells is mainly determined by the percentage of calcium carbonate in it. In order to […]
Method 1 Titration For the titration, it is necessary to dilute the Sodium Hydroxide so that it is an easier concentration to titrate. Using a 25cm3 pipette, washed out with some of the NaOH solution, transfer 25cm3 of the solution to a 250 cm3 volumetric flask, and fill to the line with distilled water. The […]
Iron is a transition element, and all transition elements may be found in a variety of oxidation states, for example, iron exists as both, Iron(II) and Iron(III). These kinds of elements can react with both oxidizing and reducing agents due to the fact that they can be converted from one oxidation state to another. Working […]
The volume of iodine solution needed to neutralize the sodium thiosulphate. You simply titrate the sodium thiosulphate against the solution of iodine using starch solution as an indicator. Then when you have calculated the concentration of the sodium thiosulphate can use it in turn as a standard solution, to find the concentration of the other […]
Hydrated FeSO4 can come in many hydrated forms. Using two methods for better accuracy and to make a comparison, I will deduce the number of water molecules per mole of a hydrated iron sulphate sample. Method 1: FeSO4. nH2O(s) ½ FeSO4(s) + nH2O(l) =dehydrating the FeSO4 by evaporating the water and calculating the mass lost. […]
I was provided with a solution of a monobasic (monoprotic) acid. Monoprotic acid is an acid that contains only one hydrogen atom. I was to determine the molarity of the acid by titration with a sodium hydroxide solution, and then use this molarity to calculate the relative formula mass of the acid. An acid is […]
A balanced equation of the reaction:Ca(OH)2(aq) + 2HCl (aq) CaCl2(s) + 2H2O(l)The aim of my experiment is to determine the concentration of a limewater solution which contains approximately 1g dm-3 of calcium hydroxide by using hydrochloric acid as a reagent in a titration.Safety ProceduresThe following safety procedures should be notified first to ensure the safety […]
The best way to determine the concentration of a solution is by a titration, and as limewater (Ca(OH)2(aq)) is a base an acid/base titration would be most useful:Ca(OH)2(aq) + 2HCl(aq) 2H2O(l) + CaCl2(l)Precautions to take: working with chemicals, e.g. corrosive hydrochloric acid, means goggles should be worn as well as an apron to protect clothes […]
Vitamin C is of vital significance in the metabolism of most organisms, however interestingly the primates including monkeys and man, guinea pigs and the Indian fruit bat are the only known higher species to be susceptible to the lack of the vitamin However micro-organisms do not form this chemical. In other words ascorbic acid is […]
One of the more common reactions seen in chemistry is the acid/base reaction. The most common result of an acid/base reaction is the formation of water and a salt. Such a reaction can be highly useful in the analysis of an unknown acid or base. By titrating the unknown analyte with a standard reagent, several […]
Honors Chemistry Titration Lab Write-up Introduction Titration Is a method, which Is meant to find the concentration of either an acid or a base by adding a measured amount of It to a known volume and concentration of an acid or Basel . Titration starts with a beaker or Erlenmeyer flask containing a very precise […]
An investigation into the total acid content of assorted brands of lemon and lime soft drink Abstract: The aim of this experiment was to determine the total levels of carbonic acid concentration in 3 differing brands of lemon and Lime soft drinks. Research Question: Does the acid content in three different lemon and lime flavored […]
Our results show that for the 1st and 2nd trial the volume of the base added are identical, but the solution’s color differs. A primary standard solution should: Be of high purity Remain unrelated in air while weighing and remain stable (no reaction or decomposition) during storage Have a high molar mass. The higher the […]
Abstracter is important substance for all living organisms. The physical and chemical properties of water play a central role in biological structure and function of the organism. The nomination ability of water to form H+ and OH- ions make it very unique. The hydrogen-ion concentration of biological system is usually preferred as the pH system, […]
There are four significant regions in titration curves: the initial point, pre-equivalence point, equivalence point, and post-equivalence point. Each region’s characteristics are related to the pH results obtained, and the points are named according to their position relative to the equivalence point. The equivalence point is where the solution becomes neutral, which is represented on […]
This project was done with the aid of a lot of people. I take this chance to express my gratitude to Mrs. . Handmaid Bit. Mad for the guidance and motivation that contributed tremendously to this project. My thanks and appreciations go to my friends in developing this project too. TITLE Analysis of Vitamin C […]
This graph indicates that as the time increases the concentration of sulfur dioxide in wine also increased. This opposed the hypothesis as it was predicted that as the time increased the concentration of sulfur dioxide in wine would decrease. Conclusion: The purpose of this experiment was to see how the concentration of sulfur dioxide as […]

Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base naturalization reaction. We will also determine the unknown concentration of the strong base Noah by its reaction with a […]
In order to create the sodium hydroxide solution, its pellet-form was dissolved in deionized water. The concentration of ethanol varied in each trial, with 25 mol% and 35 mol% concentrations used in the reactor. In order to determine the rate constant, 10 ml samples were taken every 10 minutes for an hour during the reaction […]
The purpose of this experiment is to measure the concentration of a sulphuric acid solution, which ranges from 0.05 to 0.15mol/dm?. To achieve this, I will use an alkali with a known concentration to titrate the unidentified sulphuric acid solution. The indicator phenolphthalein will be used to indicate when the acid is neutralized. The necessary […]
