Calamansi typically has a pH ranging from 2 to 3, indicating that it is quite acidic. When using an eggplant indicator, which contains anthocyanins that change color based on pH levels, calamansi juice would likely turn a reddish color, signifying its acidity. This visual change confirms the low pH of calamansi, aligning with its known tart flavor profile.

What is the color of the indicator when it mixes to calamansi?
When an indicator mixes with calamansi, it usually turns a pink or reddish color. This color change is due to the change in pH level caused by the acidic nature of calamansi juice.
What is the pH of Calamansi?
Calamansi juice typically has a pH range of 2.2 to 2.4, making it acidic in nature.
How do you make a eggplant indicator?
To make an eggplant indicator, you can use a simple process involving an eggplant and a pH indicator solution. First, cut the eggplant into small pieces and blend it with water to extract its natural pigments. Strain the mixture to obtain a liquid that can serve as a pH indicator. This natural indicator will change color depending on the acidity or alkalinity of the solution it is mixed with, typically turning purple in neutral solutions and shifting to shades of pink or green in acidic or basic solutions, respectively.
What will happen to gumamela as indicator mix to calamansi juice?
If gumamela turns purple, it indicates that the calamansi juice is acidic. If it turns green, it indicates a neutral pH. If it turns pink or red, it indicates the calamansi juice is alkaline.
What is the pH value of eggplant?
The pH value of eggplant typically ranges from about 5.5 to 6.5, making it slightly acidic. This acidity is due to the presence of organic acids in the fruit. The pH can vary slightly based on the specific variety of eggplant and its ripeness.
What is a chemical dye that changes color based on the pH of a solution called?
A chemical dye that changes color based on the pH of a solution is called an pH indicator.
What is the pH level of calamansi?
Roughly estimated at pH = 2.5 - 3 Taste: acid between lemon and orange.
What colour should sodium sulphate be in universal indicator?
Sodium sulfate is typically colorless in universal indicator. Universal indicator is a pH indicator that changes color based on the pH of a solution, and sodium sulfate is a neutral compound that does not significantly affect the pH.
Will the pure calamansi juice reach pH 0?
No, pure calamansi juice will not reach a pH of 0. The pH scale ranges from 0 to 14, with 0 being the most acidic. Calamansi juice is acidic due to its citric acid content, but it typically has a pH of around 2-3, not as low as 0.
How can the pH of a solution be measured?
pH can be measured using a pH meter, pH strips, or pH indicator solution. A pH meter provides a numerical value for pH, while pH strips or indicator solution change color based on the pH of the solution being tested.
How do you make a pH indicator not using red cabbage?
A pH indicator can be made out of grape juice or beetroot or even eggplant. Grate 1/4 cup of beetroot or eggplant into 2 cup water, boil for 10 min and strain for the dark liquid, by the way grape juice could be used right out of carton. Add indicator to the substance that is being tested, it will be more red for pH of 2 and greener for pH of 12, and test for better knowledge of all colors that pH indicator can turn.
