Strong Electrolytes
A strong electrolyte is a substance that completely dissociates into ions when it dissolves in water, resulting in a high electrical conductivity. Strong electrolytes are important in many chemical and biological processes, and are commonly used in laboratory and industrial settings.
Answer
A) Ca(NO3)2 is a strong electrolyte.
Explanation
Calcium nitrate, Ca(NO3)2, is a soluble salt that completely dissociates into Ca2+ and 2NO3- ions in water. As a result, Ca(NO3)2 is a strong electrolyte that conducts electricity well in solution.
B) HCN is a weak electrolyte.
Hydrogen cyanide, HCN, is a weak acid that partially dissociates into H+ and CN- ions in water. As a result, HCN is a weak electrolyte that conducts electricity poorly in solution.
C) H2SO3 is a weak electrolyte.
Sulfurous acid, H2SO3, is a weak acid that partially dissociates into H+ and HSO3- ions in water. As a result, H2SO3 is a weak electrolyte that conducts electricity poorly in solution.
D) NH4OH is a weak electrolyte.
Ammonia, NH3, is a weak base that reacts with water to form ammonium ions, NH4+, and hydroxide ions, OH-. However, the reaction is incomplete and NH4OH is a weak electrolyte that conducts electricity poorly in solution.
