### Understanding pH: Multiple Choice Question

#### Question: 
All of the following statements about the pH scale are true EXCEPT:

1. ⭕ Cola drinks are very acidic.
2. ⭕ The difference in concentration between pH 10 and pH 12 is 20.
3. ⭕ Neutral is pH 7.00.
4. ⭕ Blood is slightly basic.
5. ⭕ pH 2 is a strong acid.

#### Explanation:
The question is testing your knowledge of the pH scale and related concepts. The pH scale is used to measure how acidic or basic a substance is. It ranges from 0 to 14, with 7 being neutral, numbers less than 7 indicating acidity, and numbers greater than 7 indicating basicity (alkalinity).

- **Cola drinks are very acidic**: This is true. Cola drinks typically have a pH around 2.5, making them quite acidic.
- **The difference in concentration between pH 10 and pH 12 is 20**: This is false. The pH scale is logarithmic, not linear. Each whole pH value below 7 is ten times more acidic than the next higher value. Hence, pH 12 has a hydrogen ion concentration 100 times lower than pH 10.
- **Neutral is pH 7.00**: This is true. At pH 7, the concentration of hydrogen ions equals that of hydroxide ions, which is neutral.
- **Blood is slightly basic**: This is true. Blood typically has a pH around 7.4, which is slightly basic.
- **pH 2 is a strong acid**: This is true. Substances with a pH level below 3 are considered strong acids.
