“Why can overdraining coastal freshwater supplies lead to saltwater intrusion?”

Coastal freshwater supplies are vital for a whole multitude of urban areas around the world. However, if they become overdrained, then they can can lose water pressure, allowing for nearby seawater to encroach in and cause contamination. This is Why Overdraining Coastal Freshwater Supplies Can Lead to Saltwater Intrusion.

“What exactly causes ionic compounds to be dissolved in dipole solvents?”

 

One of the first facts one will learn in a Chemistry course is that ionic compounds such as salt (NaCl) will dissolve in dipolar solvents. However, have you ever wondered why does this phenomena take place? Well, as scientifically minded people, we should explore anything that we don’t know. Ionic compounds are held together by ionic bonds, which are the result of two or more atoms sharing electrons. And since these ionic bonds depend upon factors of charge distribution, they susceptible to the influence of external electric forces. As such, if they come into close contact to polar substances such as dipole solvents, the resulting ion-dipole force would rip apart the compounds.
