Question

Describe a method you could use to obtain crystals of potassium nitrate from potassium nitrate solution.
You should include an explanation of how the crystals are produced from the solution.

Answer 1

learn to do your own work.

Answer 2

Explanation:

Potassium nitrate is a chemical compound with chemical formula ${KNO}_3$. The shape of potassium nitrate is orthorhombic or regular prism.

Potassium nitrate has a large solubility difference in hot and cold water 2460 gram per litre at 100 degree celsius and 133 gram per litre at 0 degree celsius. Firstly we can dissolve potassium nitrate in hot water, and then let the water cool down.

On the either side, the quantity of nitrate will be greater than water is able to dissolve. So, the excess will come out from the solution as in the form of crystals. Crystals are usually formed by the microscopic particles and growing by regular layers of atoms are bond to one another.
