Indicators Experiment. indicators are substances that change colour when they are added to acidic or alkaline solutions; a ph indicator is a substance which has one colour when added to an acidic solution and a different colour when added to an alkaline solution. They are usually weak acids or bases, but their conjugate base or acid forms have different colors due to differences in their absorption spectra. In this practical, students make an indicator from red cabbage. Ph indicators are a good way to easily and. Try this demonstration to create a rainbow effect using universal indicator, hydrochloric acid and sodium hydroxide. The experiment is in two parts. Using indicators to measure ph. in this activity you will use red cabbage to make what is called an indicator solution. In this part of the experiment you will use five indicators to determine the ph of four solutions to within one ph unit. Indicator solutions can change colors. cabbage indicator yields a particular color depending on the ph of the solution. Various colouring materials in plants can act as indicators. indicators are substances whose solutions change color due to changes in ph.
