Litmus paper is red for acidic solutions and is blue for basic solutions.
i think its acid
In Acid the red litmus stays red but in a base the litmus changes to blu
it has (red acid) and a (blue base)
there are many types of acid base indicators - see chart at http://chemistry.about.com/library/weekly/aa112201a.htm Common indicators: Methyl orange - acid=red, base=orange Bromcresol green - acid=yellow, base=blue Bromphenol blue - acid=yellow, base=blue Phenolphthalein - acid=colorless, base=red it is also easy to use litmus paper - acid=red, base=blue
Litmus paper, phenolphthalein, and red cabbage juice are substances that change color in response to changes in acidity or basicity. Litmus paper turns red in acid and blue in base, phenolphthalein is colorless in acid and pink in base, and red cabbage juice turns red in acid and blue in base.
Blue litmus turns red in the presence of an acid and remains blue in the presence of a base.
an acid
Red Bull is slightly acidic due to the presence of citric acid and phosphoric acid in its ingredients.
Red litmus paper remains red when dipped into an acid. Blue litmus paper will turn red in an acid. Similarly, Blue litmus remains blue in a base. Red litmus turns blue in a base.
The DIFFERENCE ?! I think you mean distinguish an acid from a base, which needs an indicator, like red cabbage solution(turns yellowish with acid, darker with base) Phenolphtaline(Turns violet with a base) Red/Blue litmus paper(RLP turns blue with a base, and BLP turns red with an acid) and finally a pH meter/paper.
Litmus paper usually turns either blue or pink (sometimes red) which indicates whether the chemical is an acid or a base. If the paper turns blue it is a base. If pink or red it is an acid.
Litmus paper. If it turns red it is an acid. If it turns blue it is a base.
