Question

Classify each of these soluble solutes as a strong electrolyte, a weak electrolyte, or a nonelectrolyte. Solutes Formula Hydrochloric acid HCl Calcium hydroxide Ca( OH) 2 Hydrofluoric acid HF Methyl amine CH3NH2 Potassium chloride KCl Methanol CH3OH Sucrose C12H22O11 .Drag the appropriate items to their respective bins.

Answer 1

Answer:

The list of strong, weak and non-electrolytes is given below from the examples listed in the question.

Explanation:

A strong electrolyte would completely or almost fully dissociate or in aqueous solution; strong acids and bases are generally examples,as well as salts. The following are strong electrolytes:

• Hydrochloric acid, HCl
• Calcium hydroxide, Ca(OH)2
• Potassium chloride, KCl

A weak electrolyte would only partly be ionized in solution;  major examples are weak acids and bases. Examples of such include:

• Methylamine, CH3NH2
• Hydrofluoric acid, HF

A non-electrolyte will not dissociate in aqueous solution. The following are non-electrolytes:

• Sucrose, C12H22O11
• Methanol, CH3OH

Answer 2

Answer:

HCl - strong electrolyte

Ca(OH)₂ - strong electrolyte

HF - weak electrolyte

CH₃NH₂ - weak electrolyte

KCl - strong electrolyte

CH₃OH - nonelectrolyte

C₁₂H₂₂O₁₁ - nonelectrolyte

Explanation:

A compound that is completely ionized in water is a strong electrolyte, a compound that is partially ionized in water (1-10% solubility) is a weak electrolyte and a nonelectrolyte isn't ionized in water. Strong bases and acids are strong electrolytes. Weak acids and bases are weak electrolytes. Salts are strong electrolytes.

HCl is a strong acid, that means is a strong electrolyte

Ca(OH)₂ is a strong base, that means is strong electrolyte

HF is a weak acid, thus, is a weak electrolyte

CH₃NH₂ is a weak base, thus, is a weak electrolyte

KCl is a salt, thus, is a strong electrolyte

CH₃OH is not ionized in water when dissolved, thus, is a nonelectrolyte

C₁₂H₂₂O₁₁ is not ionized in water, thus, is a nonelectrolyte
