Homework Answers
The factors that should be considered when choosing a chemical are -
Action time.
Safety.
Price.
Microbe range.
Penetration.
Preparation.
Odor.
Action time is the time needed for a chemical action after it's applied.
Safety is the impact of the chemical on your body.
Microbe range is the effect of the chemical on microbes. The effect varies on different microbes.
Penetration means how much effect it can get into a cell.
Odor is the smell of chemical which could irritate.
Price is the cost of the chemical.
hope the answer helps.

In this experiment we are testing the effect of different chemical concentrations on microbial growth. Let’s say instead we used a 1.0% solution of Bleach against a low, medium, and high amount of microbes. How would you expect the growth numbers to look in this experiment? In restaurants, most food contact surfaces are smooth and lack cavities/pores in their surface. What is the advantage of that for microbial control? If soaps are not powerful at killing microbes, why are they used...
