Dissociation of Water Water can sometimes split into

two ions.

In pure water the concentration

of each ion is 10-7 M

Page 39: Should we control a chemical that: u Causes excessive sweating and vomiting. u Is a major component in acid rain. u Can cause severe burns in its gaseous.

Adding certain solutes disrupts the balance between the two ions.

The two ions are very reactive and can drastically affect a cell.

Example:

For a neutral solution:

[H+] is 10-7

or - log 10-7

or - (-7)

or 7

Page 49: Should we control a chemical that: u Causes excessive sweating and vomiting. u Is a major component in acid rain. u Can cause severe burns in its gaseous.

Comment

[H+] + [OH-] = 14 Therefore, if you know the

concentration of one ion, you can easily calculate the other.
