Acids and Bases Chapter 24
Acids… Definition: When an acid dissolves in water, H+ ions (charger particles) are formed H+
Acids… H + ions join with H 2 O to form hydronium compounds H 3 O +
Acids… Properties of Acids: 1) tastes sour
Acids… Properties of Acids: 2) Corrosive- can eat away at metals
Acids… Properties of Acids: 3) Can make special compounds called INDICATORS change color. Litmus paper turns RED
Acids… Properties of Acids: 4) Can burn skin
Acids… Examples: Citric acid in fruit Lactic acid in milk Acetic Acid in Vinegar Stomach Acid Battery acid….
Acids… Dissociating (Breaking Up) in Water: HCl + H 2 O H 3 O + + Cl-
Acids… Strength Strong acids are substances that completely dissociates in water to form as many H+ ions as possible
BASES… Definition: Forms OH- (hydroxide) in water and accepts H+ ions to make water –OH-
BASES… Properties of Bases: 1) tastes bitter
BASES… Properties of Bases: 2) NOT corrosive 3) Also reacts with indicators, LITMUS paper turns BLUE
BASES… Properties of Bases: 4) Can burn skin
BASES… Properties of Bases: 5) Feels slippery
BASES… Examples: Bleach, ammonia Borax Eggs Salt Water Some medicines like milk of magnesia Some other soaps
BASES… Dissociating (Breaking Up) in Water: NaOH + H 2 O Na + (aq) + OH- (aq) Aq = in water (Aqueous)
BASES… Strength: Completely dissociates in OH- ions
Fit these Examples into the Acid/Base categories Tomatoes HNO 3 Magnesium oxide Mg(OH) 2 Oranges HCl Car battery NaOH Antacid Bleach Ammonia (NH 3 ) Italian Salad Dressing

Chemical Reactions Chapter 13. Acids Have a sour taste. Vinegar owes its taste to acetic acid. Have a sour taste. Vinegar owes its taste to acetic acid.
Acid Anything that increases the hydronium ion (H 3 O + ) concentration.
Precipitation reaction – reaction in which an insoluble product forms Precipitate – an insoluble solid that separates from the solution Solubility – maximum.
