What is the best way to statically charge an object,

Static electricity can be created by rubbing one object against another object.

Explanation: This is because the rubbing releases negative charges, called electrons, which can build up on one object to produce a static charge

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.
