Science Starter
• Workbook pages

Acids and Bases
• Acids and Bases Song

Demonstration
• It’s Magic!!• Phenolphthalein is an
indicator of acids (colorless) and bases (pink).

Acids
• Tastes sour• Reacts with metals
and carbonates• Turns BLUE litmus
paper red• H+ (hydrogen ion)
Hydrochloric Acid
HCl
Sulfuric Acid H2SO4
Acetic Acid HC2H3O2
Acids produce hydrogen ions in water

Bases
• Taste bitter• Feels slippery• Turns RED litmus
paper blue• OH¯ (hydroxide ion)
Sodium Hydroxide
NaOH
Potassium Hydroxide
KOH
Aluminum Hydroxide
Al(OH)3
Bases produce hydroxide ions in water

pH Scale
• Acids and Bases Video
• Measures the concentration of hydrogen ions in a solution.
• Ranges from 0-14– 0=Acid– 7= Neutral– 12=Base

pH
• A low pH – concentration of hydrogen ions is high.(0)
• A high pH – concentration of hydrogen ions is low. (14)

Neutralization Reaction
• An acid plus a base produces a salt and a water.
HCl + NaOH NaCl + H2O
