Why do the stemless funnel, beaker and fluted filter paper need to be put in the oven?Question 5Answera.Kill microorganisms through heatingb.Smooth filtration processc.Ensure cleanliness of itemsd.Avoid crystallization on filter paper
Solution
The stemless funnel, beaker, and fluted filter paper are placed in the oven for several reasons:
a. Kill microorganisms through heating: High temperatures in the oven can kill any microorganisms present on these items. This is important in experiments where the presence of microorganisms could affect the results.
b. Smooth filtration process: Heating these items can help in the filtration process. For example, if you are filtering a hot solution, using a cold funnel could cause the solution to cool and crystallize prematurely, clogging the filter. Pre-heating the funnel can prevent this.
c. Ensure cleanliness of items: Besides killing microorganisms, heating these items in the oven can also help remove any residual chemicals or substances that could interfere with the experiment.
d. Avoid crystallization on filter paper: If the filter paper has any moisture on it, this could cause the substance being filtered to crystallize on the paper. Heating the paper in the oven can remove this moisture.
