Question
Chapter 7, Problem 4STP
Interpretation Introduction
Interpretation:
The incorrect option showing the property of NaCl from the high strength of its ionic bonds needs to be identified.
Concept introduction:
Ionic bond is formed through the exchange of valence electron(s) between atoms. It creates two ions which are oppositely charged. The metal releases electrons in ionic bonds and become positively charged while the nonmetal gains electrons to become negatively charged.
Expert Solution & Answer
Answer to Problem 4STP
Option D is the incorrect option.
Explanation of Solution
Reason for correct option: D. Low solubility. Ionic solids are soluble in water and other polar solvents because water is a highly polar solvent, the oxygen atom of the water molecule carries a partial negative charge and strongly attracts the positively charged Na. Similarly, the hydrogen atom from water carries a positive charge and strongly hold negative chloride ion. Once NaCl dissociates into its free ions, water molecule completely surrounded each ion. Low solubility is not a true statement related to sodium chloride. Therefore, it is the correct answer.
Conclusion
Reason for incorrect option:
- Ionic solids are hard and brittle. They are strongly bound with oppositely charged ions. So, they are difficult to separate, if enough external force is applied on them then they are splits. The hardness of the ionic solid is due to the strength of its ionic bond. This is a true statement. Therefore, it is an incorrect answer.
- Due to the strong attraction between oppositely charged ion, all ionic solids has high boiling points. This is a true statement. Therefore, it is an incorrect answer.
- Due to the strong attraction between oppositely charged ion, all ionic solids has high melting points. This is a true statement. Therefore, it is an incorrect answer.
