The Process of Preparing Sodium Antimonate
Sodium antimonate is an inorganic compound that contains both sodium and antimony. It is a common compound used in electronics, construction, and cosmetics, and it can also be used for medical purposes. The preparation of sodium antimonate is a multi-step process that involves several different chemical reactions. This article will outline the steps involved in preparing sodium antimonate.
The first step of the process involves creating a solution of sodium hydroxide (NaOH) and antimony trichloride (SbCl3). This can be done by dissolving the antimony trichloride in water and adding sodium hydroxide until the pH of the solution reaches 8-9. At this point, the solution should look clear.
The next step is to evaporate the solution. The solution should be heated until it begins to boil and then the heat should be reduced until it is just simmering. It is important to keep stirring the solution during this process in order to prevent the solution from burning or crystallizing. The process should be allowed to continue until the solution is reduced to a third of its original volume.
Once the evaporation process is complete, the solution is filtered and the solids are discarded. The resulting liquid is then cooled and the temperature should be reduced until it is at room temperature. This will allow the reaction between the sodium hydroxide and antimony trichloride to take place, resulting in the formation of sodium antimonate.
The final step of the process is to separate the solid sodium antimonate from the liquid phase. This can be done by filtering the solution through a filter paper and then washing the solids with water. The solids should then be dried in a large container and then stored in a sealed container in a cool, dry place.
Sodium antimonate is a versatile compound with a variety of uses. It can be used for electronics, construction materials, and cosmetics, as well as for medical purposes. The preparation of sodium antimonate is a multi-step process, but the steps outlined above can be used to successfully create this compound.
