I tells you if the fat has been digested or not. It starts purple and when digestion occurs it turns pink.
Litmus solution is a mixture of dyes dissolved in water.
Sodium sulfate solution is neutral; the red litmus is purple.
Litmus paper can be used to determine if a solution is acidic or basic
The indicators in litmus are extracted from lichens; the color of litmus depends on the pH of the solution.
Red litmus paper turn blue in basic solutions; sodium carbonate solution is basic.
nope actually, it stays blue and when u dip it in with red litmus paper it went blue, i did experiment so i kno << it would then be: alkali
To prepare a litmus solution in the lab, you can dissolve powdered litmus in distilled water to create a purple solution. Stir the mixture well to ensure the litmus is fully dissolved. Adjust the concentration of the solution by adding more litmus or water as needed.
Litmus does not change color in sugar solution.
Litmus paper turns blue in basic solution.
When neutral litmus solution is added to an alkaline solution, the litmus solution will turn blue. This change in color indicates that the solution is basic or alkaline in nature. Litmus paper is commonly used as an indicator to determine the acidity or alkalinity of a solution.
Red litmus turn to blue in basic solutions.
Litmus solution is a mixture of dyes dissolved in water.
Dip the litmus paper into the solution you are testing. Hold it up in the air, holding the dry bit. Look at the bit you dipped. If the solution was an acid, red litmus will stay red, blue litmus will turn red. If the solution was an alkali, red litmus will turn blue, blue litmus will stay red. If the solution was neutral, red litmus will stay red, blue litmus will stay blue.
Ammonia is a base, and will turn red litmus blue.
So you can tell if the solution is an acid or a base
If you mix litmus solution with an alkali, the litmus solution will turn blue. Litmus is a pH indicator that turns red in acidic solutions and blue in alkaline solutions.
No, basic solutions turn litmus dye blue. Litmus is a pH indicator that changes color in response to a solution's acidity or basicity.
