Question

How will you distinguish among sodium chloride, potassium chloride and calcium chloride?

Answer 1

Hint:Calcium chloride is a soluble compound and sodium carbonate is also a soluble ionic compound, and will react to form calcium carbonate. The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a Bunsen burner. The heat of the flame excites the electrons of the metal ions, causing them to emit visible light. Every element has a signature emission spectrum that can be used to differentiate between one element and another.

Complete step by step answer:
Sodium chloride, potassium chloride and calcium chloride will distinguish by using the flame test. Flame test is useful to determine the difference between one element and another. Sodium chloride obtained yellow flame, Potassium chloride obtained violet flame, calcium chloride obtained Brick red flame. Due to flame colors we will distinguish the difference of these salts.

Additional information:
Sodium chloride is a naturally occurring mineral found in the earth and comes from underground salt mines or solar evaporation. Potassium chloride works in softeners the same way sodium chloride does but replaces the hard water minerals with potassium instead of sodium. Calcium chloride has been widely used as a preservative and firmness.

Note: Here we remember that flame tests are useful to determine the difference between salts. Excitations produce a signature line emission spectrum for an element. In comparison, incandescence produces continuous band light with a peak dependent on the temperature of the hot object.
