Any substance with a pH of 7.
A substance that turns bitter and causes cabbage juice to turn bluish green is a strong base, such as sodium hydroxide (lye). When cabbage juice, which contains anthocyanins that act as a pH indicator, is exposed to a base, it changes color due to the alteration in pH. The bitterness is a characteristic of many alkaline substances.
Green
If you were testing a neutral substance with cabbage juice, which contains anthocyanins, the solution would typically remain purple. This indicates a neutral pH, around 7, as the cabbage juice is sensitive to changes in acidity and alkalinity. In contrast, acidic solutions would turn it red, while basic solutions would shift it to green or yellow.
It will turn either blue or green, both a hue of blue. The reason of this is that Red Cabbage Juice is an indicator, which is used to see wether an object or chemical is an acid or a base. If the object is an acid it will turn a hue of pink, and if it is a base, it will turn a hue of blue. Which is why a base mixed with Red Cabbage Juice will turn green.
Alkalis turn red cabbage juice blue/green/yellow.
blue-pinky colour.
It will turn either blue or green, both a hue of blue. The reason of this is that Red Cabbage Juice is an indicator, which is used to see wether an object or chemical is an acid or a base. If the object is an acid it will turn a hue of pink, and if it is a base, it will turn a hue of blue. Which is why baking soda mixed with Red Cabbage Juice will turn blue or green.
Blue/green color
When soda pop is mixed with cabbage juice, the color change depends on the acidity or alkalinity of the soda. If the soda is acidic (like most colas), the cabbage juice may turn a reddish or pinkish hue. If the soda is more alkaline, the color can shift towards green or blue. This reaction occurs due to the natural pH indicators present in cabbage juice.
It will turn a red color indercating that is has got acid in it
no it reacts only with rainbow cabbage juice and not red
To neutralize purple cabbage juice, which is a natural pH indicator, you can add an acidic substance such as vinegar or lemon juice. The acidity will change the color of the juice from purple to pink or red, indicating that the pH has become more acidic. Alternatively, adding a basic substance like baking soda will turn the juice green or blue, showing a shift towards a more alkaline pH. Always add the neutralizing agent gradually and mix well to observe the color change.
