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.
Calamansi juice typically has a pH range of 2.2 to 2.4, making it acidic in nature.
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.
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.
A chemical dye that changes color based on the pH of a solution is called an pH 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.
Roughly estimated at pH = 2.5 - 3 Taste: acid between lemon and orange.
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.
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.

An indicator is a substance that changes color based on the pH of a solution. It shifts its color based on whether the solution is acidic, neutral, or basic. Examples of indicators include litmus, phenolphthalein, and bromothymol blue.
An indicator can provide exact pH if you are using the neutralization titration. Paper strip pH indicator are not an exact measurement but a high, medium, and low indication of acids and bases.
