Ionic Compounds | MCQs

Explanation

• NaCl is also known as Sodium Chloride, or common table salt.
• It is a classic example of an ionic compound, where sodium (Na) loses an electron to become a positively charged ion (cation), and chlorine (Cl) gains an electron to become a negatively charged ion (anion).

Explanation

KCl (potassium chloride) is a salt.

Specifically a neutral salt formed by the reaction of an acid (HCl) with a base (KOH).

Explanation

• In a NaCl crystal lattice, each sodium (Na+) ion is surrounded by six chlorine (Cl-) ions, forming an octahedral geometry.
• This means that each Na+ ion is coordinated by six Cl- ions, and vice versa.

Explanation

• At room temperature, most ionic compounds are crystalline solids, meaning they have a rigid and orderly crystal structure.
• This is because the strong electrostatic forces between the oppositely charged ions hold them in a fixed position, creating a three-dimensional lattice.
