Storyboard Text

  • Lets go order a hamburger meal with a lemonade because I am always starving after school.
  • So, if I get a lemonade and the pH is 2.5,than the concentration of H+ is .0032m.
  • Today in class we learned about Arrhenius law. If an acid contains hydrogen and ionizes to produce hydrogen ion, but if it’s a base that contains a hydroxide group and ionizes to make a hydroxide ion in a solution.
  • Some examples that follow Arrhenius law is HCl(l)→H+(aq)+Cl-(aq), H2O(L)→2H+(aq)+O-(aq), and NaOH(s)→Na+(aq)+OH-(aq).
  • That caused Bronsted-Lowry to expand this thought by stating that if a base doesn't contain an OH- than the acid is a hydrogen donor and the base is the hydrogen acceptor.
  • Some examples that follow Bronsted-lowry's law is H2SO4 +Mg→HMg+ + HSO4-, HCl + H2O→H3O+ +Cl-, and HNO3 + Li →HLi+ +NO3-
  • With using this theory, you can reverse the reaction. Here's an example we did class HCl(acid) + Mg(base) → HMg+(conjugate acid)+ Cl( conjugate base).
  • Jamie, i not feeling so great. I think it's the lemonade.
  • I heard that baking soda calms an aching stomach. We could also use apple cider vinegar.
  • Excuse me sir, but do you have some baking soda in the back?
  • Yes we do, i be right back.
