Today in science we did experience with litmus paper.

Litmus is a tree lichen fungi and is made into small paper strips or a liquid for testing acids or allalines.

1. Blue Litmus paper determines if something is aicdic. It tuns red in soluions with a pH less than?

2. Red litmus paper determines if something is alkaline. It turns blue in solutions with a pH greater than 7.

Materials 

1. Red Litmus paper 

2. Blue Litmus paper 

3. Sodium Hydroxide 

4. Hydrochloric acid 

5. Pipette 

6. four test tubes

Steps

One: Rip the litmus paper in half and put half in each test tube 1.

Two: Add 3 drops of hydrochloric acid to the red litmus paper in the tube 2 .

There: Add  3 of hydrochloric acid to the blue litmus paper in test tube 3 .

Four: Add 3 drops of sodium hydroxide to the blue litmus paper in test tube 4 .

Five: add 3 drops of sodium hydroxide to the red litmus paper in test tube 5 .
