BI110 Lecture Notes - Lecture 5: Ionic Bonding, Hydrophile
Document Summary
An ionic bond (an ion donated an electron, & the other ion accepted it) on its own is strong if it shared its electrons. Sodium chloride; one actually took the electron so it has a strong bond. It"s attracted to the partial negative charge (it"s not donating the electrons, but it"s just being attracted) The magnesium can easily associate & disassociate itself with oxygen. A bond is formed; evident thru the dotted lines. A lot of solutes are able to dissolve in water ph scale: Your body knows what ph it should be at. Basic ph = more hydroxyl ions, less protons. 7. 4 is the ph that experiments are done on, to mimic the body (pure water has a ph of 7) Too high or too low ph can be harmful. Hydrophobic: it gets away from water (doesn"t like it)
