4. neutral solutions have a ph of 7. (click to select)▼
5. solutions with a ph greater than 7 are acidic. (click to select)▼
6. buffers help maintain ph homeostasis. (click to select)▼

Explanation:

1.

The pH scale measures hydrogen ion ($\ce{H+}$) concentration, not oxygen. So this statement is false.

By definition, the pH scale is a logarithmic scale that indicates the concentration of $\ce{H+}$ ions in a solution. So this statement is true.

The standard pH scale typically ranges from 0 (most acidic) to 14 (most basic). So this statement is true.

Answer:

False
