Here are the essential concepts you must grasp in order to answer the question correctly.
Ionic Compounds
Ionic compounds are formed when atoms transfer electrons, resulting in the creation of positively and negatively charged ions. These compounds typically consist of a metal and a non-metal, and their properties include high melting and boiling points, as well as electrical conductivity when dissolved in water.

Solubility Rules
Solubility rules are guidelines that help predict whether an ionic compound will dissolve in water. Common rules include that most alkali metal salts and nitrates are soluble, while many carbonates and phosphates are not. Understanding these rules is essential for determining the solubility of specific compounds.
