Properties of Acids & Bases By: Ms. Bowie
Acids are substances that: Taste sour!
Property #2 Acids turns blue litmus paper red! Drop of acid on the litmus paper!
Property #3 An acid will NEUTRALIZE a base. That means that the pH of the base will drop down to around pH 7. H + + OH - H 2 O
Property #4 Acids conduct ELECTRICITY. ACID
Property #5 Acids react with active metals to produce hydrogen gas. HCl + Zn ZnCl + H 2 Note that precious metals like gold and platinum are not ACTIVE and do not react with acids.
Property #6 Acids react with carbonates to produce CARBON DIOXIDE GAS. HCl + baking soda CO 2 + …. (sodium bicarbonate ).
Properties of Bases
Bases are substances that: Taste bitter!
Property #2 Bases feel slippery! Or “Soapy”
Property #3 Bases turns red litmus paper blue! Drop of base on the litmus paper!
Property #4 A base will NEUTRALIZE an acid. That means that the pH of the acid will rise to around pH 7. H + + OH - H 2 O
Property #5 Bases also conduct ELECTRICITY. BASE
That’s All Folks!

ACIDS AND BASES
Chemistry Notes: Acids and Bases
Acids and Bases. Properties of Acids: Properties of ACIDS: 1. tastes sour.
The chemical of life. Acids Sour taste, leaves burning sensation Increase hydrogen ions (H+) in solution.

TCAP Review Lesson 17 Vocabulary Foldable (IX)
ACIDS AND BASES. ACIDS & BASES Acids are substances that produce hydrogen ion in solution. (H + (aq) ) Bases are substances that produce hydroxide ions.
Acids & Bases.
Pg of composition notebook. Acid: Substance that donates Hydrogen ions (H + ) to a solution. Or forms H 3 O + (hydronium ions) with water
Acids and Bases.
Exploring Acids and Bases What are the properties of acids and bases?
Acids and bases. acids Always contain hydrogen. Always contain hydrogen. Strong or weak acids. Strong or weak acids. Common properties Sour Sour Gritty.
1 Acids and Bases. 2 Acids React with certain metals to produce hydrogen gas. React with bicarbonates to produce carbon dioxide gas Have a bitter taste.
Describing Acids and Bases
Acids and Bases. Properties of Acids þ Produce H + (hydrogen) ions in water þ Taste sour þ Corrode metals þ React with bases to form a salt and water.
Integrated Science II. Question What is the pH of pure water?
Acids and Bases. A. Definitions 1. Acid releases hydrogen ions (H + ) 2. Bases release hydroxide ions (OH - ) 3. pH scale – measures how acidic or basic.
