Do engraving yourself but ask a student to choose design.

3. 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. 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 →

9. Think Fast! Form a team of three people.
Each team needs a single sheet of paper and a writing utensil.
Once I name a category, you will have exactly one minute to list as many items in that category as possible.
Points will be awarded for relevant list items that only your team thought of.
