Question

Classify each of these soluble solutes as a strong electrolyte, a weak electrolyte, or a nonelectrolyte. Solutes Formula Nitric acid HNO3 Calcium hydroxide Ca(OH)2 Acetic acid H3CCOOH Methyl amine CH3NH2 Potassium chloride KCl Ethanol C2H5OH Glucose C6H12O6

Answer 1

Answer: Strong electrolytes:$(HNO_{3})$ Nitric acid, $(Ca(OH)_{2})$)Calcium Hydroxide and (KCl) potassium chloride

Weak electrolytes: $(CH_{3}COOH)$Acetic acid and $(CH_{3}NH_{2})$ Methyl amine

Non-electrolytes:$(C_{2}H_{5}OH)$Ethanol and $(C_{6}H_{12}O_{6})$Glucose

Explanation: Electrolytes are those compounds which can conduct electricity when dissolved in any polar solvent.

Strong electrolytes are those compounds which completely ionise when dissolved in polar solvent and hence produce ions in solution . So greater the capacity of an compound to ionize itself greater number of ions would be present in solution and hence greater will be the capacity of the solution to conduct electricity.

Ionic compounds like $(HNO_{3})$ Nitric acid ,(KCl) Potassium chloride and $(Ca(OH)_{2})$)Calcium hydroxide are completely ionized  when dissolved in polar solvent so these compounds are strong electrolytes.

Weak electrolytes are those  compounds which undergo partial ionization when dissolve in polar solvents . So they are not able to produce more ions in the solution and hence the conductivity of a solution containing weak electrolytes is low.

$(CH_{3}COOH)$Acetic acid and $CH_{3}NH_{2}$Methyl amine are partially ionized when dissolved in polar solvent so these electrolytes are weak electrolytes.

Non-electrolytes are those compounds which are not at all ionized in the polar solvent and they remain as molecules itself even if they are dissolved.

$(C_{2}H_{5}OH)$Ethanol and  $(C_{6}H_{12}O_{6})$Glucose do not ionize when dissolved in polar solvent and remain as molecules itself so the solutions of these compounds will not have ions and hence they would be unable to conduct electricity.
