General Chemistry II Lab (CHEM 1106) Determination of the Solubility Product Constant of a Salt Date Performed: March 1‚ 2011 INTRODUCTION If solid KHC4H4O6 is added to a beaker of water‚ the salt will begin to dissolve. The amount of solid diminishes‚ and the concentrations of K+(aq) and HC4H4O6-(aq) in the solution increase. When no KHC4H4O6 dissolves‚ the concentrations of K+(aq) and HC4H4O6-(aq) will not increase further and any additional KHC4H4O6 added after this point will remain

Ocean Acidification SDI: Solubility of CO2 in different temperatures Aim: To observe the solubility of CO2 in different temperatures Hypothesis: We hypothesise that in cold water the level of co2 absorption will be greater than warm water which will mean the air space in the cylinder will be less compared to warm water. Independent: Type of water. Dependant: room temperature‚ amount of water‚ type‚ size and amount of tablet‚ amount of water in the basin. Materials: 250ml graduated

Task 3: Tests for Anions: An Anion is an atom which is negatively charged therefore indicating a larger amount of electrons than proteins. Overall the tests for anions were mainly conclusive however 6 out of 8 of the anions we were testing for could only be determined from one specific result for example if a black precipitate formed following the tests the substance is therefore a sulphide however the same result would also show the presence of carbonate and hydrogen carbonate this therefore

Alcohol Lab Data Conclusion Objective: The objective of this lab was to find the concentration of an unknown alcohol solution. Procedure and Data: We found the masses of 10.00 mL of each of the known concentrations of alcohol (minus the beaker mass) by placing the beaker onto the scale‚ zeroing the scale‚ and then pouring alcohol into the beaker‚ repeating for each different concentration solution. Then‚ using the same method‚ we found the mass of 10.00 mL of the unknown concentration. We recorded
