Many household cleaning products and soaps are slippery. This is an indication that they are: a. acidic and would turn blue litmus paper red b....

The properties and characteristics of acids and bases are as follows:

Acids

• Conduct electricity


• Taste sour


• React with and neutralize bases


• React with active metals to produce hydrogen gas


• pH is less than 7

Bases

• Conduct electricity


• Taste bitter


• React with and neutralize acids


• Feel slippery 


• pH is greater than 7

Therefore, we would expect household cleaners and soaps to be bases.

Litmus Paper

Litmus is a colored organic dye. Litmus has a pH range of about 4.5 to 8.3. Litmus paper can be either blue or red.

• When red litmus paper is placed in an acid, it will remain red.


• 
  When red litmus paper is placed in a base, it will turn blue.


• When blue litmus paper is placed in an acid, it will turn red.


• When blue litmus paper is placed in a base, it will remain blue.

Therefore, we would predict that cleaning products and soaps would turn red litmus paper blue.

The answer is b.
