Ionic Compounds and Electrolytes

The video tutorial covers aqueous solutions and solubility, explaining how substances dissolve in water to form homogeneous mixtures. It details the dissociation of ionic compounds into ions, highlighting the concept of strong electrolytes and their ability to conduct electricity. The tutorial also discusses the behavior of polyatomic ions in solution, using silver nitrate as an example, and contrasts this with the insolubility of silver chloride.

What does the abbreviation 'EQ' stand for in the context of aqueous solutions?

• Dissolved in water

• Equation

• Equal

• Equilibrium

What happens to ionic compounds when they dissolve in water?

• They form a new compound

• They remain intact

• They dissociate into individual ions

• They evaporate

What is a strong electrolyte?

• A substance that dissociates completely into ions

• A substance that evaporates quickly

• A substance that does not conduct electricity

• A substance that partially dissociates in water

Why is pure water not a good conductor of electricity?

• It lacks ions to carry the charge

• It is too pure

• It has too many ions

• It is too dense

What is the role of ions in conducting electricity in a solution?

• They dissolve the electrodes

• They carry the electrical charge

• They block the flow of electrons

• They prevent conduction

What is the main difference between a strong electrolyte and pure water in terms of conductivity?

• Strong electrolytes do not conduct electricity

• Pure water conducts electricity better

• Strong electrolytes conduct electricity due to ions

• Pure water has more ions

What happens when silver nitrate dissolves in water?

• It forms a precipitate

• It dissociates into silver and nitrate ions

• It remains as a solid

• It evaporates

How do polyatomic ions behave in a solution?

• They evaporate

• They form new compounds

• They remain intact as a unit

• They dissociate into individual atoms

What is the composition of the nitrate ion in silver nitrate?

• Nitrogen and chlorine

• Nitrogen and oxygen

• Nitrogen and hydrogen

• Oxygen and hydrogen

Why is silver chloride considered insoluble in water?

• It forms a strong electrolyte

• It evaporates

• It does not dissociate into ions

• It dissolves completely
