Acid-Base Titrations A Titration of Potassium Hydroxide Phthalate and Sodium Hydroxide Hanna Piper Department of Chemistry‚ SUNY College at Brockport‚ Brockport‚ NY 14420 Chemistry 205.06 Abstract Titrations are used to find the molarity of an unknown solution. A titration begins with an analyte and titrant being used to measure the unknown molarity of the analyte. In the following experiment‚ sodium hydroxide was used as the titrant and potassium hydroxide phthalate was used as the

Anna Powell 2nd I.Title: Acid-Base Titrations AP Chemistry Laboratory #6 II.Purpose: The purpose of this experiment is to standardize a sodium hydroxide solution and use the standard solution to titrate an unknown solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant‚ Ks‚ of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus

Period G Interspecific and Intraspecific Plant Competition Abstract A study was conducted to address the problem of interspecific and intraspecific competition among wheat and mustard plants. It was hypothesized that increasing the plant density‚ and therefore increasing intraspecific competition‚ would negatively impact the plant biomass. It was also hypothesized that interspecific competition would have a stronger negative effect on the plant biomasses. This was tested by planting varying

Cost Accounting – Classification of costs Cost accounting refers to a process of accumulating‚ recording‚ classifying and analyzing all costs incurred at various levels of production. The purpose of cost accounting is manifold. It provides a final selling price‚ suggests the best possible course of action where maximum savings are possible and a strategy for future. Cost accounting is also constructive in comparing the input and output results that ultimately aids the management to arrive at a financial

housing respectively.2 Until 1953‚ the government has been adopting a laissez-faire3 attitude towards housing policy‚ leaving housing allocation in the hands of market. The Hong Kong Housing Society‚ established in 1948 with the aim to provide low-cost housing was the only governmental organization which was responsible for housing policy during the relevant period. The year 1953 should be recorded as the milestone in the development of Hong Kong’s housing policy‚ for the first public housing
