Is potassium chloride a solid or gas?

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?

Is carnallite a mineral of chlorine?

Carnallite is an evaporite mineral a hydrated potassium magnesium chloride. It is variably colored yellow to white,reddish or blue. It occurs with a sequence of potassium and magnesium evaporite.

How many different metals are present in carnallite?

How many metals are in carnallite?

Solution : Carnallite is `MgCl_(2). KCl. H_(2)O`. Hence, it consists of three different compounds, i.e., `MgCl_(2), KCl` and `H_(2) O`.

Is potassium chloride a liquid?

Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste.
