To determine the most basic household cleaner among the options provided, we need to consider the pH values of each substance:
- Household Bleach: pH 11
- Baking Soda: pH 13
- Toothpaste: pH 8
The pH scale ranges from 0 to 14, with lower values indicating acidity and higher values indicating alkalinity (basicity). A substance with a pH greater than 7 is considered basic, while a pH less than 7 is acidic.
Among the three substances, baking soda has the highest pH of 13, making it the most basic household cleaner. It is known for its cleaning properties due to its ability to neutralize acids and remove dirt and grime effectively.
In contrast, household bleach, with a pH of 11, is also a basic substance but not as basic as baking soda. Toothpaste is the least basic option with a pH of 8, which makes it only mildly basic.
In summary, baking soda is the most basic household cleaner among the substances listed.
