Determination of Water in a Hydrate DESIGN – Aspect 1: Defining the problem & selecting variables Research Question: What percentage of Copper Sulfate Hydrate is water? Background Information: There are many ionic compounds that contain one or more waters of hydration in their formulae. They exists either in anhydrous or hydrated form. Most anhydrous compounds have a strong tendency to absorb water from the humidity in the atmosphere and shifts into a hydrated form. Because of

seventh most populous worldwide. Thanks to its natural resources‚ especially oil‚ its economy is among the fastest growing in the world. From 1901 until its independence in 1960‚ Nigeria was a British colony. Great Britain decided to grant Nigeria its independence because after World War II Nigeria’s economy was very poor.

H2O2(aq) I2(aq) + 2H2O2(l). The rate law determined experimentally is rate= k[I-]1.017[H2O2]0.927. Additionally by performing essentially the same experiments but with temperature changes one can determine how k is affected by temperature changes and the new activation energy. Also‚ from graphs the activation energy was determined to be 33.3 kJ/mol. INTRODUCTION: The rate of a chemical reaction often depends on reactant concentrations‚ temperature‚ and the presence of a catalyst. Additionally

ELM 8100 Segment 2 The Logic of “Disrupting the Status Quo” Action research is known by many other names‚ including participatory research‚ collaborative inquiry‚ emancipatory research‚ action learning‚ and contextural action research‚ but all are variations on a theme. Put simply‚ action research is “learning by doing” - a group of people identify a problem‚ do something to resolve it‚ see how successful their efforts were‚ and if not satisfied‚ try again. While this is the essence of the

THE GRAVIMETRIC DETERMINATION OF SULFATE Learning Goals. 1. To determine the amount of Sulfate in an Unknown sulphate sample. 2. To perform and develop skills in precipitation Gravimetric method of quantitative analysis. DISCUSSION: Gravimetric analysis is one of the oldest analytical techniques and for this reason is referred to as a "classical method." Gravimetric procedures are usually very accurate‚ but more tedious than other methods. The only major equipment needed

Experiment #6: Colorimetric Determination of pH Almira‚ Faerie Carleen Lucile L. Gallardo‚ Charlotte O. Group #6‚ Chemistry 18.1‚ MHEG1‚ Ma’am Arlou Angeles September 23‚ 2013 I. Abstract The acidity of the four unknown solutions were determined with the use of colorimetry using McIlvaine’s buffer solutions varying in proportion of its constituents (disodium phosphate and citric acid). These buffer solutions were subjected to the addition of corresponding pH indicators and the variation of
