Discussion: This experiment highlighted the significance of pH indicators and buffers in both chemistry and daily life. , your lab report). Flavin is the pigment in red cabbage that produces the red colour shift (an anthocyanin). The acidity of a solution can be expressed using the pH scale. Firstly, use a filter paper (or coffee filter) and dip it in the concentrated solution obtained from red cabbage. 1. These distinctive color changes have made it possible to use red cabbage leaf extracts to prepare a standard set of uniquely colored reference solutions that extend over the pH range of 1 to 13. Key steps include chopping red cabbage and blending it with water to make an extract, filtering the extract to make "pH paper", then using drops of test substances on the pH paper to observe color changes which indicate acidity or basicity This document summarizes an experiment using red cabbage as a natural pH indicator. Time: 45 minutes–1 hour; Be safe. Acids and Bases: Acids, bases, and salts are three classes of compounds that form ions in water solutions. Compare the colour of the solution against the pH scale. Once it is blended, filter out the leaves inside the mixture with the strainer and pour the mixture into a large container. red cabbage. The color of the cabbage indicator will change to red or pink if the solution is an acid and it will change to green or yellow if it is a base. Temperatures have a significant effect on the cell membranes permeability and integrity. The pigment turns red in acidic environments with a pH less than 7 and the pigment turns bluish-green in alkaline (basic), environments with a pH greater than 7. Blend for several seconds. Add more cabbage if a darker color is desired.
