Notes
The student will:Distinguish between an acidand a base
The student will:Recognize indicators thatcan be used to help identifyacids and bases
The student will:Use 4 different indicators toidentify whether a substanceis an acid or base
The student will:Identify “pH”Describe what pH is and howit has a meaningful effect onus
Acid BaseIndicator pHpH ScaleChemical Property ReactivityCombustibility Flammability
Let’s Go!
A group of compoundswhich contain hydrogenand produce HydrogenIons (H+) when dissolvedin water.
Acids taste sour,conduct electricityand corrode metals.
Acid compounds’ chemical formulasalways begin with an H (a singleHydrogen atom) i.e. (HCl = Hydrochloric Acid)
A group of compoundsthat producehydroxide ions in asolution.
Bases taste bitter, feelslippery, corrodemetals and conductelectricity.
Base compoundsalways end with anOH (NH4OH) = Ammonia
