1) Substances that dissociate nearly 100% in solution to produce a conducting solution of ions are called _______________
2) Substances that dissociate only a small extent in solution to produce a conducting solution of ions are called _______________
3) Substances which do not produce ions when dissolved in solution are called _______________
1. strong electrolytes
2. weak electrolytes
3. non-electrolytes
1) Substances that dissociate nearly 100% in solution to produce a conducting solution of ions are called strong electrolytes. To identify strong electrolytes, you can look for compounds that are known to fully dissociate into ions when they dissolve in water. Some common examples include strong acids like hydrochloric acid (HCl) and sulfuric acid (H2SO4), as well as strong bases like sodium hydroxide (NaOH) and potassium hydroxide (KOH).
2) Substances that dissociate only a small extent in solution to produce a conducting solution of ions are called weak electrolytes. These compounds partially ionize when they dissolve in water. Examples of weak electrolytes include weak acids like acetic acid (CH3COOH) and weak bases like ammonia (NH3). To identify weak electrolytes, you can look for compounds that are known to partially dissociate into ions when they dissolve in water.
3) Substances that do not produce ions when dissolved in solution are called nonelectrolytes. Nonelectrolytes can be either molecular compounds or nonionic substances. Examples include sugars like glucose (C6H12O6), alcohols like ethanol (C2H5OH), and many organic compounds. When these substances dissolve in water, they remain as intact molecules and do not generate ions. To identify nonelectrolytes, you can look for compounds that are known to exist as neutral molecules in solution and do not conduct electricity.
