Presentation Transcript

  1. Reactions of acids and bases…

  2. Neutralization… • Acid + Base  salt and water Ex. HNO3 + NaOH NaNO3 + H2O Which is the acid? Which is the base? How do you know? How to best neutralize a strong acid spill?

  3. Remember the pH scale… Label strong acids, strong bases, weak acids, weak bases, neutral substance

  4. Reaction of metal with an acid… • Metal + acid  salt + hydrogen gas • Ex. Na + HCl NaCl + H2 • Is the equation above balanced? • Demo of this (and don’t try this at home) metal and acid reaction

  5. Reaction of metal with water… • Alkali metal + water  base + hydrogen gas • Ex. Li + H2O  LiOH + H2 • Is the equation above balanced? • Why can’t I do this demo in class? this is why...
