Test for boron with curcumin

Want to test whether the soil sample or a water sample contains boron, watch this video. As shown in the video, the first step is to create test specimens of various concentrations using a simple turmeric and ethanol solution as a base for comparison. The basis of this experiment is the fact that curumin present in turmeric reacts with boron to form a reddish compound and so the result of this reaction can easily be verified visually. The solutions of varying boron concentrations are created using measured amounts of borax and water. Three drops of turmeric solution are then added to each of the samples. As these solutions contain varying amounts of boron, varying amounts of reddishness will be observed in those samples.
