- Both solutions are bases
- Both solutions are acids
- Baking soda is acid and bleach is a base
- The baking soda is a base, and the bleach is an acid.
Hint:
Both solutions are basic
The correct answer is: Both solutions are bases
The pH of water determines how acidic or basic it is. The scale runs from 0 to 14, with 7 being neutral pH is less than 7 indicate acidity, while pHs greater than 7 imply baseness. The pH of water is a measure of the relative number of free hydrogen and hydroxyl ions.
