Before Wed., Sept. 21, Acids and Bases

Before school on Wednesday, Sept. 21:

  • Watch the three videos below (11 min, 5 min, 9min)
  • Complete the notes. If you did not get a copy in class, you can download it here.
  • Make a comment or ask a question
  • ALSO–there will be an entrance quiz on Wed. on molecular, complete ionic, and net ionic equations.

  1. In these videos I learned the difference between strong and weak acids (strong being anything that dissociates completely in a solution) and broadened my definition of acids (anything that donates a proton) and bases (anything that accepts a proton. I learned what strong meant compared to what concentrated meant in terms of acids and bases, and learned how to determine acid strengths based on a diagram. I also learned how to tell if ionic and molecular substances would be strong or weak electrolytes based on if they were strong or weak acids or bases (in the case of molecular substances) or if they were soluble or insoluble (if they were ionic substances). I learned about neutralization reactions and how to write the chemical equation of a neutralization reaction.

    Question: Do the group 1 and 2 metals form strong bases because they have a low electronegativity?

  2. In the video, we went more in depth of acids and bases and summarized the electrolytic behavior of soluble and molecular compounds

    Question: Can you simplify the net ionic equation as H(aq) + OH(aq) -> H2O (l) ?

  3. I learned that a strong acid or base disassociates completely. A concentrated acid or base has a lot of that same substance. Weak acids or bases do not break up completely. I learned how to show an acid or base is weak by drawing an equation and having arrows go on both sides. I also learned that a salt is an ionic compound.

  5. Today we learned how to distinguish between strong/weak acids and bases. We were also given a chart with names of strong acids and bases. We also learned about the electrolyte behavior of common soluble ionic and molecular components We also learned that salt is not an acid/base, it’s an ionic compound We also learned about neutralization reactions and how it makes water and a salt.

    Question: Can someone give an exact definition of a neutralization reaction?

  6. In these videos, I learned that strong acids and bases are anything that breaks up completely in solution, and weak acids and bases are anything that does not break up completely in solution. Concentrated means having a large amount of it.

    Are strong bases also strong electrolytes? Would strong bases be ionic or molecular? When you say that acids are anything that donates a proton and bases are anything that accepts a proton, are you only talking about Hydrogen? Or can other protons like Carbon or Sodium be donated and given away too?

  7. I learn that acid is a substance then donates proton and base is a substance that accept a proton. Strong means dissociate completely in water and weak means does not break up completely

    Question: if something is not an acid, not a base, and not an ionic compound(salt), then it will have non electrolyte and will not dissociate in water?

  8. I learned the difference between and acid and a base. Acids donate protons and bases accept protons. Then, I learned what strong and weak meant in terms of chemistry.
