occurs between molecules with O-H, N-H and F-H bonds

Question 15

describe ion dipole

Answer 15

occurs between ions and polar solvents

Question 16

polar covalent

Answer 16

electrons are shared unequally due to larger differences in electronegativity

Question 17

non polar covalent

Answer 17

electrons are shared relatively equally due to similar electronegativity values.

Answer 18

substances that minimize changes in the concentrations of H+ and OH-

Question 19

how does a buffer work?

Answer 19

accepts H+ from solutions when in excess and donate H+ to solutions when depleted
