Explain interms of binding why sodium sulfate is soluble in water where as lead Ii sulphate is insoluble
Sodium sulfate is soluble in water because it forms strong ion-dipole interactions with water molecules. When sodium sulfate is dissolved in water, the sodium ions (Na+) and sulfate ions (SO4^2-) are surrounded by water molecules, which interact with the charged ions through electrostatic forces.
On the other hand, lead II sulfate is insoluble in water because it does not form strong enough ion-dipole interactions with water molecules. Lead II ions (Pb^2+) have a larger size and greater charge density compared to sodium ions, which makes it more difficult for water molecules to surround and stabilize them in a solution. As a result, lead II sulfate does not dissolve in water and forms a solid precipitate instead.
