WebIn water, monoprotic acid dissolves and releases one hydronium ion. Aim: The aim of this experiment is to synthesis aspirin using Acetic anhydride and Salicylic acid, and to measure the synthesised Aspirin’s purity. By calculating the theoretical yield based upon the amount of Salicylic acid used in the reaction, one could calculate the ... WebApr 11, 2024 · The development of a new composite phase change material (PCM) was accomplished by using n-eicosane, which was belonging to the paraffins. For this goal, hexagonal boron nitride (h-BN)-loaded macroporous foams were synthesized by emulsion-templating method. The resulting foams were used as supporting materials in the … WebDraw a smooth curve of best fit. The temperature should stay constant at 69.3°C while the stearic acid is melting, but often the temperature continues to go down slowly. Why might your experimental results not show a perfect horizontal line at 69.3°C? emma fairweather
