Which statement is true about ionic compounds?A. Solid ionic compounds are good conductors of electricity.B. Ionic compounds have varying solubilities in water.C. Ionic compounds have very low melting points.D. Ionic compounds are very easy to bend.

Step 1: Define the Problem

Identify the correct statement about the properties of ionic compounds from the given options.

Step 2: Break Down the Problem

Evaluate each statement:

• A. Solid ionic compounds are good conductors of electricity.
• B. Ionic compounds have varying solubilities in water.
• C. Ionic compounds have very low melting points.
• D. Ionic compounds are very easy to bend.

Step 3: Apply Relevant Concepts

• Conductivity: Solid ionic compounds do not conduct electricity well because ions are fixed in place. However, when dissolved in water or melted, they conduct electricity due to free-moving ions.
• Solubility: Ionic compounds generally have varying solubilities in water, depending on the specific compound and its lattice energy.
• Melting Points: Ionic compounds typically have high melting points due to strong electrostatic forces between ions.
• Flexibility: Ionic compounds are brittle and not easy to bend due to the rigid lattice structure.

Step 4: Analysis, Verify and Summarize

• A is false because solid ionic compounds do not conduct electricity.
• B is true as ionic compounds can have different solubilities in water.
• C is false because ionic compounds have high melting points.
• D is false because ionic compounds are brittle, not easy to bend.

Final Answer

B. Ionic compounds have varying solubilities in water.
