Place a sample for pH measurement in a small jar, such as a baby-food jar and fill it about half full with the sample. 5 Add approximately 1. 5 ounces of the cabbage-juice indicator solution to the sample and stir it briefly with a spoon. 6 Estimate the pH by observing the color of the sample and cabbage-juice mixture. A light or dark pink solution indicates an acidic solution with pH between 2 and 4, purple or blue indicates a neutral solution of pH 6 to 8, green indicates a basic pH of 10 to 12 and yellow indicates a pH above 13. See the Resources section for a detailed color-to-pH correlation chart.
