As the PH scale decreases or increases, how does this affect the acidity?

When pH decreases acidity increases,

and if pH increases  acidity decreases.

Explanation:

1 2 3 4 5 6 7(neutral) 8 9 10

acidic                          basic

So, when pH decreases acidity increases,

and if pH increases  acidity decreases.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

d.) circle motion requires a force to give it a centripetal acceleration.
