Reef Chemistry Question of the Day #231
Brute trash cans and many other containers we use in reefing are made of polyethylene. Which of the following situations (long term) would be expected to be most damaging to a polyethylene container such as a Brute trash can?
A. The super low pH of concentrated (37%) hydrochloric acid (muriatic acid; pH about -1)
B. The super high pH of 30% sodium hydroxide in water (pH about 15)
C. The highly hydrophobic character of diesel oil
D. Exposure to 2% ozone in air
Good luck!
