Sodium Acetate Trihydrate Lab Report

In this experiment, 25 g of solid sodium acetate trihydrate was added into a large beaker. The solid was then heat for 5 minutes, where liquid formed. 6.3 mL of water and a pinch of red dye was poured into the beaker while heated for 2 additional minutes. The solution was then cooled in an ice bath for 30 minutes. The solid-liquid product was then finally poured on a pinch of sodium acetate trihydrate crystal seeds to form ethanoic anhydride. This experiment was ultimately conducted in order to find the proper ratio of sodium acetate trihydrate to water that would give the best yield.
In observational terms throughout the experiment, when sodium acetate trihydride was heated, a solid clear film formed with lots bubbling liquid. Through continued boiling, the solution …show more content…
When water and red dye was poured into the solid-liquid solution while heated, a red liquid solution was observed. After cooling in an ice bath, red crystal-like rock chunks were finally collected.
The product ultimately synthesized in this experiment from sodium acetate trihydrate and water under hot and cold conditions was ethanoic anhydride. With a 4:1 ratio of sodium acetate trihydrate to water, 100% of ethanoic anhydride was yielded. The theoretical yield of ethanoic anhydride product was 18.75 g, which was analogous to the actual yield of 18.75 g. Throughout this experiment, minimum solvent and correct heating time and temperature at medium heat were employed. The reaction, furthermore, was shown to be successful as the final product consisted of red crystal-like rock chunks, which was expected. In terms of purity, the yield of ethanoic anhydride was 100% in mathematical terms, and in observational terms, the product was exactly what was expected: red rock chunks. In this experiment, a sprinkle of solid sodium acetate trihydrate crystal seeds were set on a piece of aluminum foil before the product was placed on it in order
