Introduction: In this lab‚ we measured the acid-base strengths of seven separate organic compounds. The lab was painless to perform‚ it consisted of adding a small amount of one of the organic compounds to a well‚ and testing the pH via testing paper. The color of the paper was then analyzed to determine what the pH of the compound was. The structures were benzenesulfonic acid‚ benzoic acid‚ benzyl alcohol‚ benzylamine‚ p-cresol‚ and p-toluidine. My initial hypothesis about the acidity/basicity

Chemistry A Rap 1 4/6/12 Acid and Base Report If someone were to ask the common teenager in the US‚ “What’s acid?” they would probably respond with something akin to “It’s that one drug that makes you see stuff that isn’t really there and just kinda makes you crazy”. And if that same someone was to ask that same teenager‚ “What’s a base?” their response would most likely have something to do with either baseball‚ or freeze-tag. The thing is‚ most people don’t really understand the most common
