Matching

In the following solutions,is the [OH-] greater than,less than,or equal to the [H₃O+]?

Premises:
pH = 2
[ [ ] = 1.0 × M [ ] = 1.0 × M ] = 1.0 × [ ] = 1.0 × M M
[ [ ] = 1 × M [ ] = 1 × M ] = 1 × [ ] = 1 × M M
pH = 9
base
acid
[ [ ] = 1.0 × M [ ] = 1.0 × M ] = 1.0 × [ ] = 1.0 × M M
Responses:
less than
equal to
greater than

Correct Answer:

pH = 2
[ [ ] = 1.0 × M [ ] = 1.0 × M ] = 1.0 × [ ] = 1.0 × M M
