Acid and Bases

Slide 5

Acids

Have a sour taste. Vinegar is a solution of acetic acid. Citrus

fruits contain citric acid.

React with certain metals to produce hydrogen gas.

React with carbonates and bicarbonates to produce carbon

dioxide gas

Have a bitter taste.

Feel slippery. Many soaps contain bases.

Bases

Slide 6

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”

Slide 7

Acid Nomenclature Review

No Oxygen

w/Oxygen

An easy way to remember which goes with which…

“In the cafeteria, you ATE something ICky”

Slide 8

Acid Nomenclature Review

HBr (aq)

H2CO3

H2SO3

 hydrobromic acid

 carbonic acid

 sulfurous acid

Slide 9

Name ‘Em!

HI (aq)

HCl (aq)

H2SO3

HNO3

HIO4

Slide 10

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”

Slide 11

Some Common Bases

NaOH sodium hydroxide lye

KOH potassium hydroxide liquid soap

Ba(OH)2 barium hydroxide stabilizer for plastics
