Discovering the pH of Everyday Substances
What are the pH levels of rainwater, cola, tomato juice, and liquid drain cleaner?
Let's identify whether these substances are acidic, basic, or neutral based on their pOH levels.
Answer:
Rain Water: Acidic
Cola: Acidic
Tomato Juice: Acidic
Liquid Drain Cleaner: Basic
Acidity and basicity of substances can be determined by their pH levels, which are closely related to their pOH levels. In this case, we can ascertain the pH levels of rainwater, cola, tomato juice, and liquid drain cleaner based on the provided pOH values.
According to the given data, the pOH of rainwater is 8.5. By subtracting this value from 14 (which is the total value), we get a pH of 5.5. Therefore, rainwater is acidic.
Similarly, the pOH of cola is 11, resulting in a pH of 3. This indicates that cola is also acidic.
Tomato juice has a pOH of 10, leading to a pH of 4, classifying it as acidic as well.
On the other hand, liquid drain cleaner has a pOH of 0, leading to a pH of 14, which means it is basic.
It is important to understand the relationship between pH and acidity/basicity. A pH of 7 indicates neutrality, while values below 7 are acidic and above 7 are basic. The formula pH + pOH = 14 helps determine the pH levels of various substances.
