Two colors: red and blue.
Any acid will turn litmus paper red, Household examples would be most juices, vinegar, and carbonated drinks.
Ammonia turns red litmus paper blue, but does not have any effect on blue litmus parer, since it is a base.
Nitrogen gas (Nā) does not change the color of moist red litmus paper. This is because nitrogen is a neutral gas that does not have acidic or basic properties. Therefore, it will not cause any color change in the litmus paper.
The litmus papers are used for checking the acidic and basic nature of any substance. That's why drop of lemon juice, which is by nature acidic, turns blue litmus into red(as the property of acidic solution is to change the color of blue litmus to red). So soap solution which is by nature basic will turn red litmus into blue (as the property of basic solution is to change the color of red litmus to blue).
Any acid can do that You can use Citrus as well as the Citric Acid can do that
Any acid will turn blue litmus paper red.
Any acid will turn litmus paper red, Household examples would be most juices, vinegar, and carbonated drinks.
Any substance that's pH value over 8.0 turns red litmus to blue.
calcium hydroxide turn red litmus paper into blue because it is a base. it does not have any effect on blue litmus paper.
As any hydroxide being a strong base, it turn litmus paper blueRememberBase is Blue andaciD is reD
Blue litmus paper will remain blue in the presence of a base. There wouldn't be any change. Red litmus paper, though, will turn blue. Just remember than the result is red in acids, and blue in bases.
Ammonia turns red litmus paper blue, but does not have any effect on blue litmus parer, since it is a base.
Acids turn litmus red. Litmus paper is a pH indicator that changes color in response to the acidity or alkalinity of a solution. In acidic conditions, litmus paper will turn red, while in alkaline conditions, it will turn blue.
red
An alkaline solution, such as sodium hydroxide (NaOH), will change red litmus paper to blue. Alkaline solutions have a pH above 7, causing the red litmus paper to turn blue due to the presence of hydroxide ions that react with the indicator dye.
Potassium hydroxide is a strong base that will turn red litmus paper blue, indicating its basic nature. The hydroxide ions in potassium hydroxide react with the indicator dye in the litmus paper, causing a color change.
Litmus paper indicates the pH of a solution. Red litmus paper will turn blue in the presence of bases (alkaline solutions). A black color indicates that a chemical reaction is taking place with the litmus dye or paper, and this does not provide any information on pH. The paper may also turn white in the presence of strong bleaching agents such as chlorine or peroxides.
