Why does an aqueous solution of KCl conduct electricity?

In aqueous state, conduction is due to ions. So, those polar covalent substances which ionize in aqueous state conduct electricity.

Why does HCl conduct electricity despite it being a covalent compound?

HCl is covalent compound, yet its aqueous solution conducts electricity. Here, chlorine being more electronegative accepts electron that is being given by the hydrogen in the aqueous solution to become Cl- and H+ respectively. These charged species conduct the electricity in the aqueous solution of HCl.

Why do ionic compounds conduct electricity but covalent compounds do not?

Although solid ionic compounds do not conduct electricity because there are no free mobile ions or electrons, ionic compounds dissolved in water make an electrically conductive solution. In contrast, covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.

Why do ionic compounds conduct electricity when dissolved in water but most covalent compounds do not?

Is HCl good conductor of electricity?

Hydrochloric acid is a strong electrolyte and dissociates completely in aqueous solution. The solution contains free mobile ions which allow electric current to pass through it. Hence, hydrochloric acid is a good conductor of electricity.

Which type of bond will form between two chlorine atoms?

covalent bond
The two chlorine atoms are said to be joined by a covalent bond. The reason that the two chlorine atoms stick together is that the shared pair of electrons is attracted to the nucleus of both chlorine atoms.

How are ionic compounds different from covalent compounds?

Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other.

Is KCl aqueous?

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….Potassium chloride.
