How does salt become crystal?

Answer 1

A salt crystal (sodium chloride) is formed by the slow evaporation of water from a solution of salt. Salt isn't very soluble and so many small crystals form. The ions which make up salt arrange themselves in a perfect cube shape when there's not enough water for them to stay apart in solution.

Answer 2

Salt crystals form when sodium chloride and water molecules form and make a shape. When you add salt to something what does it do? The salt evaporates and gets smaller and smaller until it is like silt. Then they form on the end of a string or whatever experiment you are doing.

Answer 3

sea water, is boiled at high temperatures so the particles spread out into a gas the water evaporates into the air and is formed as a gas leaving the salt to form as a solid. therefore salt crystals happen.

Answer 4

Because the water evaporates, while the salt doesn't, so it's left behind, so it forms crystals because that's all that's left, which is the salt =P

Answer 5

Salt becomes crystals by evaportated water. I should know, I'm a scientist.

Answer 6

Well salt is sodium chloride which gets crystallised and then turns into salt

Answer 7

Table salt is made of many tiny crystals. When you mix these salt crystals with water, they dissolve, losing their crystalline form. When the water evaporates, the salt crystals form once again.
