[Chemical Knowledge]：How to dissolve potassium persulfate

Read： 1818 Time：18months ago Source：Transform the World with Simplicity

Potassium persulfate is a common oxidant, commonly used in organic synthesis, pulp bleaching, rubber vulcanization and other fields. However, during use, it is necessary to provide a suitable solution, otherwise its activity will be severely limited, and ultimately affect the application effect. So, how can we make potassium persulfate dissolve better?

we need to understand the basic situation of potassium persulfate. The chemical formula of potassium persulfate is K2S2O8, and the color is white crystal, which has strong oxidation and promotion effect. Potassium persulfate is readily soluble in water, and its solubility increases with increasing temperature. After dissolving in water, potassium persulfate can form a stable elemental SO4, and release oxygen at any time, produce the effect of active oxidant, cut off the chemical bonds of many organic substances, and produce some chemical changes.

According to the above characteristics, we can use the following ways to improve the solubility and activity of potassium persulfate:

1. Heating method

The solubility of potassium persulfate increases with increasing temperature. Therefore, we can dissolve it by heating it. During the heating process in the solution, we need to be careful not to increase the temperature too much, otherwise it will have an irreversible effect on the reaction.

2. stirring method

Compared with temperature, potassium persulfate is more sensitive to stirring. Therefore, when it is dissolved in water, we need to choose a suitable stirring method to improve its solubility and activity. Generally speaking, we can use magnetic stirring or mechanical stirring to achieve.

3.
of
by acid-base method The influence of acid and base is also very important in the dissolution process of potassium persulfate. Usually, we can use a small amount of acid or alkali to adjust the pH of the solution to improve its solubility. However, it should be noted that excessive acidification or excessive alkalization will affect the activity of potassium persulfate, and the appropriate value range should be maintained.

above are several ways to improve the solubility and activity of potassium persulfate, but in the process of use, we also need to pay attention to the following points:

1. Maintain oxygen ventilation

When potassium persulfate is dissolved, it is easy to release oxygen at a rapid rate. Therefore, during use, we need to maintain sufficient ventilation to avoid excessive gas concentration and danger.

2. Pay attention to safety

potassium persulfate is a harmful high-activity chemical, should strictly abide by the operating procedures, wear protective equipment. At the same time, it should be stored in a ventilated and dry place to avoid mixing with combustible substances.
