Which is not true regarding the pH scale?

The neutral pH at 25°C is 7.0.

Bases have a pH greater than 7.0.

The pH scale measures the hydronium ion concentration in solution.

When the concentration of hydroxide ions increases, the pH decreases.

I  am pretty sure about the first 3 but the 4th one idk. 

I'd go with 4th but wait for second opinion.

What do you think?
