Unit 4: Acid-Base Theory Lesson 1: Arrhenius Acids and Bases

Introductory Demo Glass-Eating Acid! Demo 12.IV.4 - 5 min Do engraving yourself but ask a student to choose design.

Arrhenius Acids and Bases The first theory concerning acids and bases was created by Svante Arrhenius. According to Arrhenius, An acid is any ionic species whose formula starts with “H” A base is any ionic species whose formula ends with “OH” 5 min

Acid-Base Neutralization Acid + Base → Salt + Water Try This: H2SO4 + NaOH → H2SO4 + Fe(OH)3 → H3PO4 + KOH → HCl + Sn(OH)4 → H2S + Ca(OH)2 → H4P2O7 + NaOH → “We” do – 10 min
