Is potassium chloride a solid or gas?

solid
Potassium chloride is an inorganic metal halide composed of a potassium ion and a chloride ion with the chemical formula KCl. It is a odorless white crystal or crystalline powder. As a solid, KCl dissolves promptly in water and its solutions have a salt-like taste.

What are chemical properties of potassium?

Potassium metal is soft and white with a silvery lustre, has a low melting point, and is a good conductor of heat and electricity. Potassium imparts a lavender colour to a flame, and its vapour is green. It is the seventh most abundant element in Earth’s crust, constituting 2.6 percent of its mass.

Is carnallite an oxide ore?

Detailed Solution. The correct answer is Potassium. Carnallite is a Potassium metal. Carnallite is having potassium (K) and magnesium (Mg) in its chemical formula, so these metals are present in an ore.

Does carnallite contain copper?
