To make a 2 percent solution, you will need to know the solute and the solvent you are working with. The term "percent solution" refers to the amount of solute (in grams) dissolved in 100 milliliters (mL) of solvent. Here's a general process for making a 2 percent solution:
Determine the amount of solution you want to make. Let's say you want to make 100 mL of a 2 percent solution.
Calculate the amount of solute needed. Since you want a 2 percent solution, you need to dissolve 2 grams of solute in 100 mL of solvent.
Measure out the appropriate amount of solute using a balance or a measuring spoon. In this case, measure out 2 grams of the solute.
Add the measured solute to a container that can hold at least 100 mL.
Add the solvent (usually water) gradually to the container, while stirring or swirling the mixture. Continue adding the solvent until the total volume reaches 100 mL. Ensure that the solute is completely dissolved in the solvent.
Label the container with the name and concentration of the solution, as well as the date of preparation.
Remember, this is a general method, and the specific steps may vary depending on the solute and solvent you are using. Additionally, if you are working with a highly concentrated solute or a hazardous substance, it is important to follow appropriate safety guidelines and protocols.
