Which of the following statements concerning ionic compounds is true?
A)Essentially all ionic compounds are solids at room temperature and pressure.
B)Ionic compounds do not contain any covalent bonds.
C)Ionic compounds contain the same number of positive ions as negative ions.
D)The chemical formula for an ionic compound must show a nonzero net charge.

Question

Quizplus · Accepted Answer

Ionic compounds are typically comprised of a positively charged metal ion and a negatively charged non-metal ion, held together by electrostatic forces. These electrostatic forces are strongest in the solid state, which is why most ionic compounds are solids at room temperature and pressure. However, there are some exceptions, such as ionic liquids. Therefore, statement A is true. Statements B and D are false, as ionic compounds can contain covalent character and the chemical formula for an ionic compound must show a net charge of zero. Statement C is partially true, as ionic compounds must have the same number of positive and negative charges overall, but individual ions may have different charges.
