The combination of compounds
Now there is sodium acetate and barium bromide, and the change of the combination of the two is desired. Sodium acetate is mild in nature and can be isolated as ions in water solubility. Barium bromide can also be soluble in water and is scattered as ions.

When the two are mixed, ions are free to swim in water. Acetate ions and barium ions, sodium ions and bromine ions meet each other. However, according to the laws of chemistry, both barium acetate and sodium bromide are soluble in water, so there is no precipitation, gas or weak electrolyte.

The two are mixed. Although ions are encountered, there is no new substance. It is only a mixture of ions in the solution. Looking at the process, it is the interweaving of ions, which does not involve fundamental changes. Only the state of ions is redistributed in the solution.
