Define natural acid-base indicator?
Nature provides us with pH indicators in the form of plant pigments known as antocyanines, which change color over different pH ranges, depending on source. The indicators derived from red cabbage and red beet are two examples. Red cabbage juice will function over a wide pH range, from as low as pH 1 up to pH 12. The following is a pH color chart for red cabbage... pH 2=red, pH 4=purple, pH 6=violet, pH 8=blue, pH 10=blue-green, pH 12 = green-yellow.
How does colour changing bubble bath work?
The bubble bath has a dye added to it called Bromocresol Green which is a pH indicator, it will change colour as you change the pH of the bathwater - how acid or alkali the solution is. (Interestingly the one colour it never goes is green!)So as you dilute the bubble bath, which starts off slightly acid, the pH then gets higher and the water becomes more alkaline, making the Bromocresol Green change from orange to blue. If the water becomes acid again it will change from blue back to orange.

3 How is the Universal indicator color chart used to measure acidity?
We measure pH by using a pH scale which has different colours on it which indicates the liquid. Universal indicator is a pH indicator that transitions through numbers 1- 14 (on a pH chart) to indicate the acidity or alkali of solution. A pH meter is an electric instrument used to measure the pH of a liquid which might be an acid neutral or an alkali. and there is my answer Lewis Jones park community school lots of substances change colour at specific pH values, so you have to use a colour chart for that specific substance. Universal indicator is a mixture of lots of different indicators so it changes colour many times throughout the entire pH range, and you can compare it to the universal indicator colour chart to find how acidic or alkaline your substance is.
How do you read PH chart?
the color of the chart represents the color that the pH test strip tuned there should be a decimal number the decimal number should be with the color so 7.0 is the normal pH level for a human
