Either donates H+ to another molecule OR increases the amount of H+ in a solution.

• buffers

• acids

• bases

• salts

• concentration

can keep the pH of a solution stable by alternately donating and accepting ions that contribute to pH.

• buffers

• acids

• bases

• salts

• concentration

Under normal circumstances fluids inside cells and bodies stay within a consistent range of pH because they are buffered

Hydrocarbons are generally non polar (hydrocarbons are basically carbons surrounded by hydrogens, ex. Lipids). Hydrocarbons tend to be in long chains or rings. Very little O and N atoms present (if at all).

• non-polar

• ionic bond

• electronegativity

• polar

• Ion

Contains a higher ratio of O, or N atoms. (These are the most common in biological molecules you will see in this course). (More electronegative, more likely to form polar covalent bonds).
