2. ACIDS.
•The Acids is a substance that produces hydrogen ions (H+) when
placed in water.
•When acids/ionic compounds are dissolved in water the ions split
apart from each other (dissociation).

3. PROPERTIES OF ACIDS.
Most acids……
•Taste sour
•React with many metals to form H2 gas
•Are corrosive (appears to “eat away” materials while reacting).
•Have a chemical formula that begins with H
Zin Metal + Hydrochloric acid → ???
Zn(s) + 2HCL (aq) → H2 (g) + ZnCl2 (aq)

4. COMMON ACIDS .
•Citric Acid.
→Found in citrus fruits. →Used as a preservative.
•Lactic Acid.
→Found in yogurt. →Produced by our muscles when they are overloaded .
•Acetic Acid.
→Vinegar →Used as a preservative.
•Carbonic Acid.
→Found in soft drinks.

5. BASES.
•A bases is a substance that produces hydroxide ions (OH) when
placed in water.
•When bases/ionic compounds are dissolved in water, the ions split
apart from each other (dissociation)

6. PROPERTIES OF BASES.
Most Bases…..
•Taste bitter.
•Feel slippery.
•Are corrosive(appears to “eat away” materials while reacting).
•Have chemical formula that ends with OH

7. COMMON BASES.
•Ammonia
→Cleaners and fertilizers.
•Sodium Hydroxide.
→Used in soaps and drain cleaners
•Magnesium Hydroxide
→An ingredient found in antacids.

8. INDICATORS.
•Indicators are used to determine if a substance is an acid or a base.
•An indicator changes a specific color when in the presence of an acid or a base.
→Litmus Paper: indicator made of a special filter paper that contains dyes extracted
from lichens (the crusty “stuff” that grows in rock).
Blue litmus turns red in an ACID.
Red litmus turns blue in a BASE.

9. PH.
•The pH scale can also help us classify solutions as acids or bases
•pH is a measure of the amount of H ions in a solution (potential hydrogen).
•The more H ions the lower the pH, the more acidic the solution.

10. STRONG / WEAK ACIDS AND BASES.
•STRONG ACID OR BASE: WHEN ALL MOLECULES OF A GIVEN AMOUNT OF AN ACID OR A BASE
DISSOCIATE COMPLETELY IN WATER TO FURNISH THEIR RESPECTIVE IONS, H+(AQ) FOR ACID AND
OH−(AQ) FOR BASE).
•WEAK ACID OR BASE: WHEN ONLY A FEW OF THE MOLECULES OF A GIVEN AMOUNT OF AN ACID OR A
BASE DISSOCIATE IN WATER TO FURNISH THEIR RESPECTIVE IONS, H+(AQ) FOR ACID AND OH−(AQ) FOR
BASE).

11. NEUTRALIZATION.
•Neutralization is a chemical reaction between an acid and a base that takes place in
water solution.
•When acids and bases react, the H ions from the acid react with OH ions the base to
form HOH (H2O-water!)
•The overall pH becomes “neutral”

12. SALTS.
•The ions that are left behind after the H and OH ions form water combine to form a
salt.
•A salt is a compound that forms when the negative ions from the acid combine with
the positive ions from the base.
Acid + Base → Water + Salt.
