Mr. Borek, thank you for checking my answers
The only reason why I didn't do all the questions is my laptop has a horrible habit of overheating and shutting down without any warning; I'm glad I sent my thread prematurely and edited it as I worked the answers out because my computer did suddenly shutdown yesterday.
Anyway, back to answers!
3B In practice, the reaction in 1A tends not to run in reverse. What does that tell you about the strength of the acid involved? Explain your answers.
My answer; That this reaction doesn't tend to run in reverse tells me that HBr- is a relatively strong acid.
4A What is stronger-- sulfuric acid or carbonic acid? (Hint; which one is responsible for acid rain?)
My answer; Carbonic acid is a relatively weak acid responsible for acid rain. Sulfuric acid is stronger.
4B Imagine you have two glasses. One contains a solution of carbonic acid. The other contains a solution of sulfuric acid. Without any other information, can you tell which one is more corrosive? Explain your answer.
My answer; No, you can't tell. The corrosive nature of acids and bases in solution is entirely a function of the hydroxide ions and the hydronium ions. There is no difference in kind between the corrosive effect of sulfuric acid and the corrosive effect of carbonic acid. Both produce corrosive hydronium ions; Sulfuric acid just produces more of them.
4C What makes an acidic solution corrosive?
Hydronium ions. How corrosive the solution is depends of the percentage of hydronium ions present in the solution.
Huh, well I guess that wasn't as hard as I thought it was, thank you for the encouragement Mr. Borek! But can you please check these too? I'd appreciate it
also, I know I didn't word these very well, so I'm very open to any suggestions. Thanks!
