Some Properties of Acids

Produce H+ (as H3O+) ions in water (the hydronium ion is a hydrogen ion

attached to a water molecule)

Taste sour

Corrode metals

Electrolytes

React with bases to form a salt and water

pH is less than 7

Turns blue litmus paper to red “Blue to Red A-CID”

Some Properties of Bases Produce OH- ions in water

Taste bitter, chalky

Are electrolytes

Feel soapy, slippery

React with acids to form salts and water

pH greater than 7

Turns red litmus paper to blue “Basic Blue”

Naming Acids and Bases

--The name of a nonoxy acid ( Acid w/o Oxygen) --Start with hydro- --Change –ide ending to –ic

Example: HBr = hydrobromic acid • HCl hydrochloric acid • HF hydrofluoric acid

Naming Acids and Bases

--The name of an oxyacid Stem of the anion (carbonate) changed to -ic

acid HNO3 nitric acid • H3PO4 phosphoric acid • H2SO4 sulfuric acid • H2CO3 carbonic acid

Naming Bases

Say the name of the cation and add hydroxide. NaOH sodium hydroxide KOH potassium hydroxide Ba(OH)2 barium hydroxide Mg(OH)2 magnesium hydroxide Al(OH)3 aluminum hydroxide Mn(OH) 2 manganese (II) hydroxide

Acid Base Reactions

Acid + Base Salt + Water NaOH + HCl NaCl + H2O KOH + HCl H2O + KCl 2Al(OH)3 + 3H2SO4 6H2O + Al2(SO4)3 Ca(OH)2 + 2HNO3 2H2O + Ca(NO3)2 Ca(OH) 2 + H2CO3 2H2O + CaCO3

H from acid and OH from base make HOH (H2O )

The elements left over make up the salt Na + Cl NaCl
