For an experiment, a student needs a compound that has the following properties.
• It dissolves in water.
• It is an electrolyte.
• It is excellent conductor of electricity.
Which substance would be the best choice for the experiment?
O methanol
O acetic acid
O distilled water
O potassium chloride

The potassium chloride would be the best choice for the experiment.

Option: D

Explanation:

KCl is soluble in a multitude of polar solvents like very soluble in water and get split into K+ and Cl-. KCl solutions are general standards for calibrating the electrical conductivity of ionic solutions, for instance, because KCl solutions are robust, enabling repeatable observations.

This is basically completely ionized in aqueous solution into solved K+ and Cl– ions. Due to its ionic property considered as excellent conductor of electricity. This is because on adding water the potassium ion approach oxygen of water while chlorine ion target hydrogen, being opposite charges.

thats a little if u want the answer just look it up on google thats what i do haha : )

the correct answer would be d. hope this !
