Question
You want to store a small amount of colored liquid to be used for chemical reaction later. Which of the following is the best laboratory tool to use?a.test tubeb.Erlenmeyer flaskc.mortard.pipette
Solution
The best laboratory tool to use for storing a small amount of colored liquid for a chemical reaction later would be a test tube (option a). Here's why:
a. Test Tube: Test tubes are ideal for storing small amounts of substances and can be easily sealed with a stopper or cap to prevent contamination. They are also made of glass, which doesn't react with most chemicals.
b. Erlenmeyer Flask: While Erlenmeyer flasks can also store liquids, they are typically used for mixing and heating substances. They are larger than test tubes and may not be ideal for storing small amounts of liquid.
c. Mortar: A mortar is used for grinding substances into a fine powder. It is not suitable for storing liquids.
d. Pipette: A pipette is used for transferring small amounts of liquid from one place to another. It is not designed for storage.
Therefore, a test tube is the best option for this purpose.
