1. Provide a comprehensive description of the experiment Thomson used to discover the electron. Thomson was experimenting with electric discharges in electric discharge tubes when he found that it would glow when a high voltage was applied in a gas volume at low pressure‚ while it was known that the glow in the gas was something to do with the cathode and the negative pole of the high voltage‚ Thomson continued with his experiments with the rays coming from the cathode and he found that the rays

The Methods of Psychology Experiment: The experiment is the most useful of all scientific methods because most of the basic facts in psychology are supplied by the results of experimental studies. This method is generally done in a laboratory setting involving many controlled variables. They are particularly effective in proving hypotheses about cause and effect relationships between variables. A hypothesis is a prediction of how one variable relates to another. There are two

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6
