Explain in your own words what is the environmental significance of pH.
Step by step
Solved in 2 steps
- Using a pH meter, you find the pH of an unknown solution to be 8.0. How would you describe this solution? a. weakly acidic b. strongly acidic c. weakly basic d. strongly basicManufacturers make carbonated drinks by forcing pressurized carbon dioxide gas into flavored water. A chemical reaction between water molecules and some of the CO2 molecules creates hydrogen ions (H+) and bicarbonate, which is a buffer. In your opinion, is this reaction likely to raise the pH of a soda above 7, or lower it? Give your reasoning.explain the importance of pH for the environment in your own words
- Describe the properties of water, and explain why it is so important in biological systems.Which of the following describes a buffer? A. The measure of the amount of hydrogen ions in a liquid B. A set of chemicals that can keep the pH of a solution stable by alternately donating and accepting the ions that contribute to pH C. A substance that releases hydrogen ions in water D. A substance that accepts hydrogen ions in waterDescribe the pH scale and how it was derived; define acid, base,and neutral levels.
- Convert the hydrogen ion concentration (moles per liter) of a solution to a pH value and describe how buffers help minimize changes in pH.Explain the difference between a solution with a pH of 5 and a solution with a pH of 3.List three other properties of water that make it an essential for living organisms
