On the Method of Potassium Acetate Reserve Solution
If you want to make a good potassium acetate reserve solution, you need to know all the elements. The first thing to choose is pure and good potassium acetate, which is the basis of the quality of the solution. For potassium acetate, its impurities must be rare in order to maintain the purity of the solution.
As for the solvent, water is the best choice. However, the water also needs to be carefully filtered to remove dust and microorganisms, etc., and pure water is appropriate. Take an appropriate amount of water, pour it into a clean vessel, and slowly add potassium acetate. When adding it, it should be slowly and evenly stirred with a glass rod to help it dissolve quickly.
When stirring, pay attention to the change of temperature. If the temperature is too high or too low, it may affect the dissolution rate of potassium acetate and the stability of the solution. At room temperature, stir carefully until the potassium acetate is completely dissolved without sediment.
After the dissolution is completed, check the concentration. It can be determined by precise measurement methods, such as chemical titration, or by advanced instruments. If the concentration does not meet the requirements, add or subtract potassium acetate or solvent as appropriate to achieve a precise concentration.
When storing, choose a well-sealed container. This can prevent the solution from coming into contact with the outside air and preventing it from being oxidized and hygroscopic. Place in a cool, dry place, do not expose to light, so that the potassium acetate reserve solution can be stored for a long time and the quality remains unchanged for various uses.
