Ionization of Water. Water molecules have a tendency to “fall apart” or dissociate “Dissociate” means to separate or disconnect from. Two water molecules. Ionization of Water. This is usually written in a simplified version. Ionization of Water.
H2O OH- + H+
How often does water disassociate to form ions?
In pure water, about one water molecule in 550 million naturally dissociatesinto a Hydrogen Ion(H+)and a Hydroxide Ion(OH-)
Because the number of positive hydrogen ions(H+)is equal to the number of negative hydroxide ions(OH-) produced, water is neutral.
What is an ion?
A polar molecule
An atom with which gained or lost protons
An atom with a + or – charge
A molecule that loses an atom
Onewater molecule in 550 million naturally dissociatesinto a Hydrogen Ion (H+) and a Hydroxide Ion(OH-)
H2O H+ + OH-
Buffers help organisms maintain the pH of body fluids within the narrow range necessary for life.
Are combinations of H+ acceptors and donors forms in a solution of weak acids or bases
Work by accepting H+ from solutions when they are in excess and by donating H+ when they have been depleted.Buffers
