    Acids Bases and Salts Acids Bases and Salts Presentation Transcript

    • Acids Bases and Salts Brainpop~Acids and Bases
    • Acid: A substance that releases H+ ions in an aqueous solution “ aqueous” means: water
    • Characteristics of Acids:
      • Acids have a sour taste
      • Acids react with metals
      • Acids contain Hydrogen
      • Many are poisonous and corrosive to skin
      H
    • Strong Acids (break down completely to give off many H+ ions)
    • Weak Acids (only partially breaks down, gives less H+) Mark Bishop Acid animation
    • Common Acids: All others considered Weak (examples) Acetic acid (vinegar) HC 2 H 3 O 2 Carbonic acid HCO 3 Weak Acid The Formula H 2 SO 4 HCl HBr HI HNO 3 HClO 4 Sulphuric acid Hydrochloric acid Hybrobromic acid Hydroiodic acid Nitric acid Perchloric acid The Formula Strong Acids
    • Base: A substance that releases OH- ions in an aqueous solution
    • Characteristics of Bases:
      • Bases usually taste bitter
      • Bases feel slippery
      • Bases contain hydroxide ions
      • STRONG bases are also poisonous and corrosive to skin
      OH -
    • Common Bases: (Hydroxides of Group 1 and Group 2 Metals are STRONG) All others are WEAK LiOH NaOH KOH RbOH CsOH Ba(OH) 2 Ca(OH) 2 Sr(OH) 2 Lithium hydroxide Sodium hydroxide Potassium hydroxide Rubidium hydroxide Caesium hydroxide Barium hydroxide Calcium hydroxide Strontium hydroxide The Formulae Strong Bases
    • Some bases (VERY FEW) don’t have OH- Most commonly: ammonia NH3
    • Reactions between acids and bases When and acid and a base react with each other, the characteristic properties of both are destroyed. This is called neutralization .
    • Reactions between acids and bases General formula for acid base reaction: Acid + Base -> H 2 O + Salt “ Salt” means any ionic compound formed from an acid/base reaction NOT JUST NaCl !! Neutralization Reaction Animation
    • Neutralization HCl + NaOH -> H 2 O + NaCl acid base water salt
    • Neutralization Another Example HNO 3 + KOH -> H 2 O + KNO 3 H OH K NO 3 acid base water salt
    • Indicators An indicator is a compound that will change color in the presence of an acid or base
      • Universal indicator (pH paper) Used for the full pH range
      • Red Litmus-Turns blue in base
      • Blue Litmus-Turns red in acid
              • Phenolphthalein-Turns pink in base
    • pH pH stands for “potential hydrogen” and is a measure of how many H+ ions there are in solution. The MORE H+ there are, the LOWER the pH will be.
    • pH Scale Shows the range of H+ concentrations High H+ concentration Low H+ concentration
