Exam question idea: “Using the quantities listed on the label calculate the pH of the buffer solution in this enema bottle.” Thoughts? #chemistry #teaching #applications #academic #enema

    @sellathechemist I assume you’d provide the pKa’s needed? I also think a good question could be ask students to write the equilibrium reactions present in the bottle. The bottle is hard to read, so maybe a typed version of the label would be more accessible.

    @sellathechemist other than telling them that the pKa is 7.20, it sounds like a good idea.

  • LOL. But, when spending long stretches of time in a hospital (not often, luckily) I do find myself calculating various values because there really can be not much else to do... I think it's a good question!

    @sellathechemist tangentially related, for anyone into mischief rolls of "for rectal use only stickers" are a great source of fun
