Experimental Objectives
The laboratory assignment aims to test the water absorption by sodium carbonate and its capability to store water. Experimental Procedure The chemicals used for the assignment are sample that consist of 60% sodium hydrocarbonate and 40% sodium carbonate, and the sample with unknown composition. During the experiment, the moisture from the sample is removed by drying and the sample is dried until the constant mass. Taking the mass difference, the quantity of evaporated water is calculated, and the composition of the unknown mixture is defined.
Weight of the unknown sampleWeight of the sample after the constant drying. Experimental Data The raw experimental results Continue reading...
