nice to practice for acid base nomenclature and pH

Labs and Activities
1. Test different household solutions and unknown lab solutions for pH with different indicators and pH paper. Then, test the unknown solutions in each of the available indicators e.g. red onion juice, red cabbage juice and universal indicator. Record the color change.
2. Titrate for unknown concentration of an acid with a known concentration of base with phenolphthalein or pH probes
3. Optional if time allows, Chromatography of Grape Kool Aid lab

Dry Ice into different acid/base indicators
Titration with CBL using pH probe

The proton



select Acid-base titration experiment or Acid-base pH meter titration experiment and practice titrations
