analyte using a solution of known concentration. Normally, the known solution (titrant) is put into a burette to a known quantity of the unknown solution (analyte) until the reaction is complete. We can tell that the reaction is complete by using an indicator which usually signals the end of the reaction by a colour change, also known as the endpoint. Alternatively, pH meters can be used to record something known as the pH difference; pH is a measure of hydrogen ion concentration of a solution. Solutions

the analysis of soda ash, the volume needed to neutralize the soda ash is used to compute for its alkalinity, in this experiment we obtained a 17.6 % alkalinity with an error of 15.14% In the analysis of a carbonate-bicarbonate mixture two indicators (phenolphthalein and methyl orange) were used. The first endpoint determines the half-neutralization of the carbonate and the second determines that of the

Summary The purpose of this experiment was to find the molarity of a concentration and the acid-base titration. In part A of this experiment, the molarity of an assigned concentration which was 0.040, was found using formulas that represent molarity. Part B of this experiment, which was titration of an acid and base, was found by a series of steps that involved dropping Sodium Hydroxide from a buret into vinegar, until the perfect shade of pale pink occurred. With the Phenolphthalein, too much

How does soil affect the pH of water? Abstract: During this lab, the pH of water in soil from a man made garden, a deciduous forest, and a river bank were tested after leaving it in containers for one, two, and three hours, coming out to a total of three trials with three different soils all together. After testing the pH of the water when being added to the soil for the desired amount of time and comparing it to the original water with no soil added, is then when each pH difference was observed

Abstract: This experiment utilizes skills of titration in order to find the percent mass of actual aspirin (acetylsalicylic acid) in store-bought aspirin. Two steps and two kinds of titrations are used. First, approximately 0.1 M NaOH solution was standardized using titration with KHP. KHP was used because it does not absorb moisture when it is stored, and it is soluble in water. The reaction that takes place in this reaction is a 1:1 mole ratio reaction. The titration determines the volume

judged to be complete. In an acid-base titration, an acid neutralizes a base or vice versa. Endpoint: The point in a titration analysis at which the addition of the titrant is stopped due to an observable colour change seen through the presence of an indicator in the sample. The colour changes is a result of rapid pH change in the sample. Equivalence point: the point in a titration analysis at which chemically equal amounts of titrant and sample (acid and base) have been combined. 4. It would be easiest

Introduction We decided to do a project concerning the acidity in organic tomatoes and commercially grown tomatoes. Originally, we wanted to use home grown tomatoes compared to commercially grown tomatoes, but unfortunately the weather is not conducive to grow tomatoes in a home garden during this time of the year. We choose this experiment because we wanted to determine if there is a significant difference in the acid of the tomatoes. In addition, in determining the acidity level of the two groups
