In class we learned about ionic compounds and the key concepts of hydrophobic and hydrophilic. Ionic compounds are basically defined as being compounds where two or more ions are held next to each other by electrical attraction. One of the ions has a positive charge which is called a cation, and the other has a negative charge which is called a anion. Cations are usually metal atoms and anions are either nonmetals or polyatomic ions (ions with more than one atom). Its the same thing when two magnets stick together. hydrophobic having little or no correspondence with water. And hydrophilic means having a tendency to mix with, dissolve in, or be wetted by water.
In class we did a lab and we tried to make magic sand, That means that we tried to make the sand water proof. By making the sand water proof were separating water and sand so they do not mix, just like how oil and water doesn't mix its basically the same thing. by using silicon we gave the sand hydrophobic properties.
When doing this project we learned that you cant just do it real fast and be lazy, scince are group didn't really take our time our sand didnt stay hydrophobic and went back to hydrophilic. Over all this expiriment didnt really go how we planned, but we did learn alot.
