Experiment #7: Acids‚ Bases and Salts Mabag‚ Viannery D.‚ Mangune‚ Paolo D. Chem 14.1‚ MAB1‚ Ms. Angelyn del Rosario March 8‚ 2010 I. Abstract The experiment allowed students to explore different electrolytes and classify them into acids‚ bases and salts by using different indicators or by measuring the pH levels of each. The experiment also helped students classify different substances through their conductivity properties. The preparation of a 1 M stock solution from NaOH pellets diluted to a

Concentration vs Rate of reaction Brandon Introduction A reaction rate is the speed at which a chemical reaction will occur. Heat‚ concentration of a chemical‚ Surface area or a catalyst‚ will affect the rate of reaction. The concentration of a chemical will speed up of the reaction because the reactant particles have become more crowded therefore increasing the chance of productive collisions. In this practical the chemicals will be Sodium thiosulphate and Hydrochloric acid which will produce

EXPERIMENT 2 ACID DISSOCIATION CONSTANT OF AN INDICATOR DYE OBJECTIVES Using spectrophotometric method: determine the wavelengths at which the acid and base forms of the dye in aqueous medium exhibit maximum absorption; determine the molar absorptivities of the acid and base forms of the dye and estimate an unknown concentration of the dye in solution using the Beer-Lambert’s Law; and determine the acid dissociation constant of the indicator dye. THEORY The absorption or reflection of

The Micro Chip Computer Corporation Shows a total of net sales for the years of 2000 – 2004. The total net sales have seemed to drop since 2000. I will compute the year-to-year percentage annual growth in total net sales by taking the current year total net sales and subtracting the previous years. I will then multiply that by 100 and then divide that by the previous year’s total net sales. This will give me the annual percentage growth. The formula will be (current year total net sales – previous

Straight blades produce regular chips while rippled blades produce ridged potato chips. * 5 The slices fall into a second cold-water wash that removes the starch released when the potatoes are cut. Some manufacturers‚ who market their chips as natural‚ do not wash the starch off the potatoes. Color treatment * 6 If the potatoes need to be chemically treated to enhance their color

The following gives way to my beliefs that the Elgin Marbles should stay at the Duveen Gallery in Britain. The first section seeks to credit Lord Elgin and a legitimate purchase. The second section revolves around the Elgin Marbles as a symbol of Greek identity and why keeping them in Britain makes sense. Finally‚ the third section focuses on the location of the antiquities in relation to
