Question
Healthy environments for life have a pH closest to
- 1
- 3
- 7
- 10
Hint:
Healthy environment has neutral pH.
The correct answer is: 7
The term pH is often encountered in chemistry as this is used to assess the acidity and basicity of different solvents and solutions. Being able to interpret pH can save you from unwanted accidents in the laboratory. For instance, if you know that a certain substance has a pH way below pH 7, then you know that it is acidic and must be handled carefully to avoid skin burns.
Healthy environments for life have a pH closest to 7.
