Determination of Water Hardness by EDTA Titration Bonnie Abella Dr. Asmita Kane Budruk 2/09/2014 Abstract: the complexometric EDTA titration was used to determine the salt substance in the water. This technique for the unknown sample 154 produced a water hardness of 8.43 x105=mg/L CaCO3 from the collected data which corresponds to the typical value from the city of Tempe. Introduction When the water from the rain collects impurities by dissolving the salt that is exist

Adsorption Experiment This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption‚ absorption and sorption are. Adsorption is the accumulation of gases‚ liquids‚ or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

Design of Experiments (DOE) Tutorial Design of Experiments (DOE) techniques enables designers to determine simultaneously the individual and interactive effects of many factors that could affect the output results in any design. DOE also provides a full insight of interaction between design elements; therefore‚ it helps turn any standard design into a robust one. Simply put‚ DOE helps to pin point the sensitive parts and sensitive areas in designs that cause problems in Yield. Designers are then

You can use dry ice‚ or as I used‚ you can use glycerin liquid and distilled water. Investigative question: Will the solution of the glycerin liquid and distilled water work in the making of the fog? Hypothesis: Depending on how much of each ingredient and how much warmth and spacing between the objects‚ the fog machine will
