sulphide etc and hence smells bad. Acetylene can be liqiufied at 0°C under 48 Torrs of pressure. The melting point of Acetylene is -81.8°C and boiling point -83.4°C. It is slightly soluble in water but highly soluble in organic solvents like alcohol and acetone. Acetylene under suitable conditions decomposes with evolution of a lot of heat and sudden increase in volume‚ which causes explosion. Hence liquid acetylene is highly explosive. ------------------------------------------------- Uses Acetylene

Leo Tran IB Chemistry SL II R5 Ms. Crane January 4‚ 2012 Restoring Balance LAB Pre-Lab Questions 1. The solubility of iodine increases because the position of equilibrium has shifted towards the triiodide side of the reaction. Addition of the reactants causes an increase in the product which is directly related to the solubility of iodine in water in this case. 2. Ammonium chloride will be more soluble in hot water as in an endothermic reaction‚ increasing the temperature (which

Exp.11) Identification of unknown ketones. Introduction: Given five samples of a known ketone derivative‚ the purpose of this experiment is to identify which unknown ketone derivative corresponds to the five known samples. In other words‚ using specific methods of compound detection‚ it is possible to match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment‚ identification of the unknown ketone is accomplished through thin
