Electrolyte Strength and Dissociation

The video tutorial explains the classification of compounds as strong, weak, or non-electrolytes based on their ability to dissociate in water. It covers the dissociation process of compounds like FeCl2, H2SO4, and HCN, highlighting the role of ions in conducting electric current. Strong electrolytes fully dissociate, while weak electrolytes partially dissociate. Non-electrolytes do not dissociate and are involved in equilibrium reactions. The tutorial also discusses the importance of understanding the dissociation process for identifying the strength of acids and bases.

What is the primary factor in classifying a compound as a strong, weak, or non-electrolyte?

• The color of the compound

• The ability to dissolve in oil

• The temperature at which it melts

• The degree of dissociation in water

When FeCl2 dissociates in water, what ions are formed?

• Fe3+ and Cl-

• Fe2+ and Cl-

• Fe2+ and Cl2

• Fe3+ and Cl2

Why is FeCl2 considered a strong electrolyte?

• It changes color when dissolved

• It fully dissociates into ions in water

• It partially dissociates in water

• It does not dissociate in water

What happens when H2SO4 dissociates in water?

• It forms H+ and SO4- ions

• It forms H2 and HSO4- ions

• It forms H+ and HSO4- ions

• It forms H2 and SO4- ions

Why is H2SO4 considered a strong electrolyte?

• It does not dissociate in water

• It fully dissociates into ions in water

• It forms a precipitate in water

• It partially dissociates in water

What is the nature of HSO4- when it dissociates?

• Strong acid

• Weak acid

• Strong base

• Non-electrolyte

What ions are formed when HCN dissociates in water?

• H2 and CN-

• H+ and CN-

• H2 and C2N-

• H+ and C2N-

Why is HCN considered a weak electrolyte?

• It fully dissociates in water

• It forms a gas in water

• It does not dissociate in water

• It partially dissociates in water

What is the significance of the equilibrium reaction in the context of HCN?

• It indicates complete dissociation

• It shows partial dissociation

• It implies a change in color

• It suggests no dissociation

What is the role of dissociation in determining the strength of an electrolyte?

• It changes the taste of the solution

• It influences the ability to conduct electricity

• It affects the temperature of the solution

• It determines the color of the solution
