Question

Identify the following substance as a strong electrolyte, weak electrolyte, or nonelectrolyte. Select the single best answer.

NaCl
a) Strong electrolyte
b) Weak electrolyte
c) Nonelectrolyte
d) Super electrolyte

Answer 1

NaCl is a strong electrolyte because it dissociates almost completely into ions when dissolved in water, enabling the solution to conduct electricity well.

Step-by-step explanation:

The substance NaCl (sodium chloride) is classified as a strong electrolyte. When dissolved in water, NaCl dissociates almost completely into sodium (Na+) and chloride (Cl-) ions, making it a good conductor of electricity. Strong electrolytes like NaCl are important in various applications, including biological processes and industrial applications where electrical conductivity is required.

Identifying whether a substance is a strong electrolyte, a weak electrolyte, or a nonelectrolyte depends on how well it dissociates into ions in an aqueous solution. Strong electrolytes dissociate completely, weak electrolytes partially dissociate, and nonelectrolytes do not dissociate into ions at all.

Regarding the provided exercise, here is how each substance would be classified:

• CH3CH2CH2OH - Nonelectrolyte
• Ca(CH3CO2)2 - Strong electrolyte
• I2 - Nonelectrolyte
• KOH - Strong electrolyte
• AgNO3 - Strong electrolyte
• CHCl3 - Nonelectrolyte
• BaCl2 - Strong electrolyte
• Li2O - Strong electrolyte
