Characteristics of Acids

Some characteristics of acids are:


1. Tastes sour

2. Reacts with certain metals to produce hydrogen gas

3. Turns blue litmus paper red

4. Reacts with limestone to produce carbon dioxide

5. Reacts with bases to form salts and water

6. Produces hydrogen ions

Examples of Acids

Some examples of acids are Binary and Oxyacids.


Binary Acids


  • Are made up of two elements only, the first being hydrogen.
  • Has only one nonmetal
  • Naming with hydro at the beginning and ic at the end


Examples: Hydrobromic Acid, Hydrochloric Acid, or Hydrophosphic Acid.


Oxyacids


  • Always contain the element oxygen
  • Are made up of polyatomic ions
  • Ends with -ate or -ite

(-ate>_ic) (-ite>ous)


Examples: Sulfous or Sulfic Acid, Phosphous or Phosphic Acid, and Nitric or Nitrous Acid.


The picture is a binary acid.

The pH Scale of Acids

Acids are always below pH 7.


The lower the pH, the more acidic or strongest.

The higher the pH, the more neutral it becomes.

The acid is at it's strongest when it is (.) something.

The acid is at it's weakest when it is (6.) something.


The picture is some common acids and their pH balance.

Characteristics of Bases

Some characteristics of Bases


1. Taste bitter

2. Feels slippery or soapy

3. Reacts with oils and grease

4. Turns red litmus paper blue

5. Reacts with acids to form salts and water

6. Produces hydroxide ions


The picture is high temperature grease.

Examples of Bases

Some examples of bases.

Examples:


  • Soap
  • milk of Magnesia
  • Tums


Strong bases are able to completely ionize in aqueous solutions.

Weak bases do not completely ionize in a solution.


Bases have a pH of 7 or more.

Having a pH of 7 means that they are no longer acidic, but basic.


The picture is of Tums.
