Caustic corrosion rates increase significantly at higher temps!

I’m pretty confident that the answer is 175 F based on what we discussed in class about high-strength caustics.

I feel like 125 F sounds familiar, but I can't recall if that's the threshold for general corrosion or just a warning level.

I practiced a similar question last week, and I believe the answer was around 150 F, but I could be mixing it up with another topic.

I think I remember something about caustic corrosion rates increasing at higher temperatures, but I'm not sure if it's 150 F or 175 F.

This seems like a straightforward question, but I want to double-check my understanding. High temperatures can accelerate corrosion in caustic solutions, so the key is identifying the specific temperature threshold mentioned in the question. I'll review the options and select the one that best fits the information provided.

Okay, let me think this through step-by-step. Exposure to high solution strength caustic can result in general corrosion, and the question is asking about the temperature threshold above which high corrosion rates occur. I'll carefully consider each option and select the one that seems most likely.

Hmm, I'm a bit unsure about this one. I know high temperatures can increase corrosion rates, but I'm not sure of the exact threshold. I'll have to think this through and make my best guess.
