Red and blue are the two colors of litmus paper. Litmus paper is used to test the pH of a substance.
Red color in acidic solutions and blue color in basic solutions.
Two colors: red and blue.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
Red litmus paper and blue litmus paper. Blue litmus paper turns red in the presence of an acid and red litmus paper turns blue in the presence of an alkali.
The natural color for litmus paper is blue. When put in an acidic solution the blue paper turns red. Red litmus paper is first mixed with an acid when it is made. This causes the paper to appear red. When put in the presence of a base, the paper returns to its natural blue color.
Litmus paper is primarily made out of paper. The paper is mostly made up of wood cellulose, which is treated with solvents beforehand to make sure there are no contaminants. Litmus paper is infused with lichens. Lichens are considered to be both an algae and a fungus, and they're quite sensitive to environmental change, which gives litmus paper its color changing ability.The two most common lichens found in litmus paper are rocella tinctoria and lecanora tartarea.- eHow.com/jseger29@yahoo.com

Litmus paper is an indicator that changes color when affected by the pH of certain chemicals. There are two colors to test the general pH of a solution. Alkaline solutions (bases) turn red litmus paper blue. Acidic solutions (acids) turn blue litmus paper red.
Red color in acidic solutions and blue color in basic solutions.

Potatoes, like the majority of vegetables, are a low-acid food with a pH value of 6.1. Each brand of pH test strips may have slightly different color schemes. Litmus paper comes in two colors. Red litmus paper turns blue when exposed to a base. Blue litmus paper turns red in the presence of an acid. Litmus paper is of limited use since it only tells you whether you are dealing with an acid or base and gives no indication about strength. Universal indicator paper would show a very light yellow. Hydrion paper would show a 'dirty' yellow.
The litmus paper is used to evaluate the pH of a solution.
Yes, litmus paper is used to tell the difference between acid and alkali - blue for alkali and red for acid
As the name implies, paper is the primary ingredient in litmus paper. The wood used to make the paper is treated with solvents to get rid of extraneous substances such as lignin and resin; it is then infused with lichen, which is interestingly two organisms--an algae and a fungus--sharing one existence. Two popular varieties of lichen are used in litmus paper, Roccella Tinctoria and Lecanora Tartarea. I is used to determine the pH of a substance (wether acidic or alkaline).
