Answer:One way to differentiate between concentrated nitric acid and dilute nitric acid is through a chemical test using copper.
1. Take a small piece of copper wire or a copper strip.
2. Dip the copper into the nitric acid solution you want to test.
3. Observe the reaction:
a. If the copper strip dissolves or reacts vigorously, producing brown gases, then the nitric acid solution is concentrated. This reaction occurs because concentrated nitric acid is a strong oxidizing agent that reacts with copper to form copper(II) nitrate and brown nitrogen dioxide gas.
b. If there is no significant reaction or a slower reaction with minimal gas production, then the nitric acid solution is dilute. Dilute nitric acid has a lower concentration of nitric acid molecules, resulting in a less vigorous reaction with copper.
It is important to note that when working with acids, appropriate safety precautions, such as wearing gloves and eye protection, should be taken. Additionally, this test should only be performed by individuals with the necessary knowledge and expertise in handling chemicals.
