Compare and contrast extensive property and intensive property

Intensive property: Does not depend on the amount of sample being examined. Some examples include: boiling point, density, and melting point.

Extensive property: depends on the amount of sample. Some examples include: mass and volume.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
