Taking the matter of sodium acetate trihydrate in water as a guide
Recently, those who have studied the state of substances in water have focused on the change between the dissolution of sodium acetate trihydrate into water. Sodium acetate trihydrate is shaped like a grain, pure and shiny in color, and has a peaceful nature.

At the beginning, take sodium acetate trihydrate and put it in water. See its gradual melting, surrounded by water molecules, dissociate into sodium ions and acetate ions. This process is quiet, without noise, and without the appearance of violent changes, such as when a person sits at a seat, quietly in place.

With the increase in the amount of dissolution, the properties of the solution gradually change. Its conductivity is gradually stronger, and edge ions can carry current in water. And because of the slight interaction between acetate ions and water molecules, the acidity and alkalinity of the solution also shift, showing a slightly alkaline nature.

Looking at the microscopic scale, the hydrogen bond between the sodium acetate trihydrate molecule and the water molecule is pulled together, just like relatives and friends. Ions swim freely in the water, colliding and clutching, following the rules of physical chemistry.

If heat is added, the solution changes differently. The solubility of sodium acetate trihydrate increases with temperature rise, and more grains melt in water. When the temperature is lowered, some solutes or recrystallization, such as the bird returning to the nest on a cold night, are arranged in the shape of crystals in an orderly manner.

From this, it can be seen that sodium acetate trihydrate in water, although there is no magnificent change, but there are thousands of changes in the microscopic world, which shows the delicacy of the material world and is also an important sign of chemical research.
