Question
A sample of seawater has a measured pH of 8.1. Classify the seawater.
- neutral
- base
- carbonate
- acid
Solution
Classification of Seawater Based on pH
-
Understanding pH Scale: The pH scale measures the acidity or alkalinity of a solution. It ranges from 0 to 14, where:
- A pH of 7 is considered neutral.
- A pH less than 7 indicates an acidic solution.
- A pH greater than 7 indicates a basic (alkaline) solution.
-
Analyzing the Given pH: The pH of the seawater sample is given as 8.1.
-
Determining the Nature of Seawater:
- Since the pH of 8.1 is greater than 7, we can conclude that the seawater is basic (alkaline).
- Oceanic environments often have pH levels slightly higher than neutral due to the presence of dissolved bicarbonates and carbonates that help buffer the pH.
-
Final Classification: Therefore, the seawater can be classified as basic.
Final Answer
The seawater with a pH of 8.1 is classified as basic.
