Verified step by step guidance1
Understand the concept of electrolytes: Electrolytes are substances that dissolve in water to produce a solution that conducts electricity. They typically dissociate into ions in solution.
Identify the types of compounds: Ionic compounds and strong acids/bases are usually strong electrolytes, while covalent compounds that do not ionize in water are non-electrolytes.
Analyze each option: (CH3)2NH2, NaOH, HIO3, C2H5OH, and CsNH2.
Determine the nature of each compound: NaOH is a strong base and dissociates into ions, HIO3 is an acid and ionizes in water, CsNH2 is an ionic compound and dissociates into ions, (CH3)2NH2 is a weak base and partially ionizes.
Identify the non-electrolyte: C2H5OH (ethanol) is a covalent compound that does not ionize in water, making it a non-electrolyte.
