Chemistry Lab Concentration Effects On Rate Of Reaction
1,070 wordsAim: The aim of this investigation is to investigate the rate of reaction of magnesium (mg) with Hydrochloric acid (HCl). After studying the availability of equipment I have chosen to investigate how concentration can affect the rate of reaction. Other variables that affect this investigation are: - Concentration of solution - Temperature - Surface area of a solid - Catalyst - Light - Pressure of a gas Prediction: I predict that when changing the concentration of hydrochloric acid and water, the...

Bunsen Burner Degrees Celsius
1,031 wordsAim: Dunder Experiments Experiment 1. Aim: To find the PH of Dunder. Materials: -Crucible -Filtrated Dunder -Universal Indicator -Eyedropper Method: A small amount of filtrated Dunder is placed in the Crucible. A few drops of Universal Indicator are then dropped onto the Dunder with the Eyedropper. The mixture will then change to colour corresponding to the Dunder's PH. Results: In this Experiment the PH of the Dunder came up as 4. This showed that Dunder is considerably acidic. Experiment 2. Ai...

20 Ml Y 2
223 wordsPurpose: The purpose of this lab was to gain the quantitative measure of the color difference between Transmitance and absorbance in 8 different samples of water containing varying amounts of iron in a range between 5 - 100 ppm, so that we know which samples where except able for drinking. Data: The Mystery Solution had a transmittance of 6 Calculations 80 ppm (25 ml) = 20 ml 100 ppm This means that in order to get 25 ml of 80 ppm solution 20 ml of water must be added to the previous solution. A...
