Question

To perform a liquid oxygen particulate test, use all of the following equipment except

a. filter paper.
b. clean white paper.
c. glass beaker.
d. aluminum or glass beaker cover.

Answer 1

For a liquid oxygen particulate test, use filter paper, clean white paper, and a glass beaker, but not an aluminum beaker cover because aluminum could contaminate the test.

Step-by-step explanation:

You asked about the equipment necessary for performing a liquid oxygen particulate test and which one is not to be used. For this procedure, you would use a filter paper, a clean white paper, and a glass beaker; however, you would not use an aluminum beaker cover. In chemistry, to maintain purity of substances being tested, especially something as reactive as oxygen, materials used should be non-reactive. Aluminum could potentially react or shed particles, contaminating the test. Instead, typically a glass beaker cover would be suitable as glass is inert and will not interfere with the liquid oxygen particulate test.
