Multiple Choice
Which of the following compounds forms an electrolyte solution when dissolved in water?
A
CH_3OH (methanol)
B
NaCl
C
CCl_4
D
C_6H_{12}O_6 (glucose)
Verified step by step guidance1
Understand what an electrolyte is: An electrolyte is a substance that dissociates into ions when dissolved in water, allowing the solution to conduct electricity.
Examine each compound's nature: Methanol (CH_3OH) and glucose (C_6H_{12}O_6) are molecular compounds that dissolve in water but do not dissociate into ions; they are nonelectrolytes.
Consider NaCl: Sodium chloride is an ionic compound that dissociates completely into Na^{+} and Cl^{-} ions in water, making the solution conductive and thus an electrolyte.
Look at CCl_4: Carbon tetrachloride is a nonpolar molecular compound that does not dissolve well in water and does not produce ions; it is not an electrolyte.
Conclude that among the given options, only NaCl forms an electrolyte solution because it dissociates into ions in water.
