Question

why are are plastic bottles commonly used to store chemicals in a chemistry laboratory ​

Answer 1

Answer:

Plastic bottles are commonly used to store chemicals in a chemical laboratory because plastics are non-reactive. They are inert to air and water. They are non-corrosive, therefore we can store chemicals in them safely.

Answer 2

Answer:

see the explanation (correct answer is there)

Because plastics, specifically polyethylene and polypropylene which are the most commonly used, are chemically inert to most substances other than strong oxidizers.

But many chemicals are stored in glass, because it’s even more chemically inert than plastic. The disadvantage: glass is much, much heavier than plastic, so your shipping costs go up. Also, there are some chemicals (like HF) that dissolve glass.

Likewise, solvents that would dissolve or otherwise weaken plastic containers are typically stored in glass or metal cans: diethyl ether, for example, tends to be sold in aluminum cans, and the same is true for THF (tetrahydrofuran, which is essentially “diethyl ether with a hair tie”).
