Lab 9: Analysis of Commercial Bleach Introduction Many common products are effective because they contain oxidizing agents. Some products‚ which contain oxidizing agents‚ are bleaches‚ hair coloring agents‚ scouring powders‚ and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (or NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized from the molecular form (Cl2) to the

sample only. In determining the SSD and oven-dry weights needed for calculation of specific gravities‚ a conical mold was used to reach an SSD condition and the sample was later dried in an oven. Sieve analysis determined the particle size distribution by sifting the aggregate through a series of eight sieves of different sixes by use of a mechanical shaker. The results found are that the aggregate used has a Bulk Specific Gravity (SSD) of 2.552‚ which indicates a normal weight‚ and Absorption of

In order to carry out a detailed stability study of OXP and CYPZ in combination‚ it is essential to have a single stability-indicating assay method which can separate both drugs along with all of their degradation products from each other. Therefore‚ a RP-HPLC method was developed and optimized. Optimization of the chromatographic conditions In this study‚ the different experimental parameters were carefully studied and optimized in order to improve the performance and system suitability parameters

Answer: Suppose two programs (NegCue and FastContext) are available and ready to run. I will put them on the same server and write a script to execute them together at the same time and record the processing time. Thus‚ the processing times of both programs will be paired for each run. By the end of the experiment‚ I will have 200 pairs of recorded processing time. Next‚ I will use paired t-test to exam rule hypothesis proposed above. Specifically‚ for example‚ let’s assume that I have recorded the

1– Qualitative Analysis of Cations Rachel Sorrells Gretchen Diede TA: Kunal Punjabi February 16‚ 2017 RESULTS & DISCUSSION The purpose of this experiment was to utilize two different methods of qualitative analysis to determine the identity of two unknown cations in an unknown solution. The experiment required knowledge of solubility rules and demonstration of such in the laboratory setting for the first method of qualitative analysis. The second method of qualitative analysis was the performance

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great
