Why should a minimal amount of water be used to cover the red cabbage leaves?
Using a minimal amount of water to cover the red cabbage leaves helps preserve the color and flavor of the cabbage. Excessive water can dilute the natural pigments and flavor compounds in the cabbage, resulting in a less vibrant and tasty final dish.
How do you make a chemistry tea indicator?
To make a chemistry tea indicator, you can use a substance like red cabbage. Simply chop the cabbage, pour boiling water over it, and let it steep to extract the color-changing compounds. The resulting liquid can be used as an indicator for acidity or alkalinity in solutions based on color changes.
Why is red cabbage used as small pH indicator?
Red cabbage contains natural pigments called anthocyanins that change color in response to changes in pH. When the cabbage is chopped up and soaked in water, the anthocyanins are released, allowing them to act as a pH indicator by changing color from red in acidic solutions to blue or green in basic solutions.
What is water lettuce?
No
What color does distilled water turn when mixed with red cabbage water?
Distilled water mixed with red cabbage water will turn a bluish color due to the anthocyanins in the red cabbage affecting the pH of the solution.
What is the lowest costing pH meter?
red cabbage is a good universal indicator you need a red cabbage hot water and a pestle and mortar put hot water into the mortar and crush the red cabbage leaves with the pestle the water should turn purple. your own universal indicator!

How do you make red cabbage indicator?
In order to make this kind of an indicator, you need: RED CABBAGE, A MIXER, WATER, STRAINER, ACID, BASE, BEAKER (or a glass). Now, take a few of the red cabbage leaves and put them in the mixer, after that, put water into the mixer. Now: MIX! When you mix, strain off the cabbage-leaf parts into a beaker and you're ready to go. If you pour hydrochloric acid, the juice turns red, if you put ammonia, it turns green, if you put a solution of sodium hydroxide, it turns yellow. Of course, these are all lab-grade chemicals. You can also use (Lemon) Citric Acid, Acetic Acid(Vinegar), Sodium Bicarbonate(Baking Soda)...Hope I helped..! :)
What is the name of the method used to separate the cabbage water indicator from the pieces of red cabbage?
Filtration
Why does cabbage indicator stay the same colour in water?
Cabbage indicator stays the same color in water because water has a neutral pH, which does not cause the indicator to change its color. The pigment in cabbage indicator changes color in response to changes in the pH level of its environment, but since water has a pH level close to 7 (neutral), there is no significant change in color.
Why does cabbage juice work as an indicator?
put small pieces of purple cabbage in hot water and stir it and leave it for 20 min and take only water. if indicator turns substance red it is acidic ,if blue then basic if no change then neutral
Why are the leaves on the inside of a cabbage paler?
because they have less water
Why is the inside of a cabbage lighter?
The inside of a cabbage is lighter due to its structure and composition. The inner leaves are typically younger, more tender, and contain more water, making them less dense than the outer leaves. Additionally, the inner part has fewer chlorophyll pigments, which contribute to a darker color in the outer leaves. This combination of factors results in a lighter appearance for the inner cabbage layers.
What is a cabbage indicator?
The phrase "cabbage indicator" refers to the use of red cabbage juice to indicate the pH of a solution. For red cabbage contains the pigment molecule ka flavin, which is an anthocyanin. In fact, anthocyanin also is responsible for the reds of certain tree leaves such as sassafras [Sassafras albidum] and sourwood [Oxydendrum arboreum]. Anthocyanin has the advantage of being a water soluble pigment. Its color varies depending upon the acidity/neutrality/alkalinity of the solution in which it's found. For example, the anthocyanin pigments in red cabbage juice turn red in acidic, purplish in neutral, and greenish-yellow in basic solutions.
What colour does red cabbage indicator go in water?
it goes bluey purpley when it is in water and red in acid and yellow - green in alkali
How can you use toothpaste to show that red cabbage is an indicator?
