Is salt an ionic bond? Is HCl an ionic bond? Is metallic bonding covalent or ionic? What is the molecular geometry of PCL3? Is sodium chloride an ionic or covalent bond? How does a covalent bond form between nitrogen and phosphorus?
If a soluble ionic compound is introduced as a solid, then it will dissolve by dissociating into an aqueous solution of its constituent ions. These ions will interact with the water molecules to depress the freezing point temperature at the same pressure. The exact freezing point depression will...
