BACKGROUND INFORMATION:

Collingwood is built up on limestone rock.

Limestone-CaCo3
-sedimentary rocks with mainly CaCO3 (calcium carbonate)
-limestone is made up almost 100% by CaCO3.
-Ontario and Quebec produce over 70% of Canada’s total limestone
 

Hydrochloric Acid (HCl)
Hydrochloric Acid is 0-1 pH
pH—to be determined with universal paper

actual chemical equation
2HCl + CaCO3     ---- CaCl2+ H2O + CO2

Vinegar

Vinegar is 3-5 pH
pH  —to be determined with universal paper

Water

water is neutral (7 pH)
—to be determined with universal paper

Acid Rain
Rain measure between 0-5 on the pH scales is acidic and is called acid rain

Acid

-substance with a sour taste
-acids turn blue litmus paper red
-pH 0-6
-strong acids can burn your skin

C=  Carbon
H=  Hydrogen
O=  Oxygen

Work:  Using 3 small stones to increase the surface area rather than one large stone for each sample
