Answer:
I would choose A
Explanation:
this is because B- not all chemicals should be kept out in the open, ready to use at any time. This can not only be unorganized but also dangerous
C- never leave an unmarked container
D- never add a substance to a chemical and then put it back in the original container
A requirement for storing chemicals is that the chemical containers should be labelled clearly.
When chemicals are not properly kept or stored, they may result in harm. For example, when a chemical isn't properly labelled, someone might take the container and open it and this can bring about harm. For example, exposure to an acid is harmful.
Option B is incorrect. Chemicals should be stored in a safe place and not where they'll be used.
Option C is incorrect. Mixed chemicals should be properly stored and not in an unmarked, clean water.
Option D is incorrect. Used for spilled chemicals should not be stored in the original container.
In conclusion, based on the explanation above, the correct option is A.
