Sure, let's analyze each substance based on its pH value.
a. Substance with pH=6:
- The pH scale ranges from 0 to 14. A pH value below 7 indicates an acidic substance, a pH value of 7 indicates a neutral substance, and a pH value above 7 indicates a basic (alkaline) substance.
- Given the pH of 6, this value is less than 7.
- Therefore, we can conclude that the substance with a pH of 6 is acidic.
b. Substance with pH=7:
- A pH value of 7 is exactly neutral.
- This is typically the pH of pure water.
- Therefore, the substance with a pH of 7 is neutral.
c. Substance with pH=1:
- Again, on the pH scale, values less than 7 indicate acidity.
- Given the pH of 1, this is very low on the pH scale, indicating a highly acidic substance.
- Therefore, the substance with a pH of 1 is acidic.
In summary:
- The substance with a pH of 6 is acidic.
- The substance with a pH of 7 is neutral.
- The substance with a pH of 1 is acidic.
