The green color denotes the presence of the element boron (B) which you’d expect in boric acid. Tests for soil pH and other qualities of soil use colored indicators, and small particles (usually clay) from the soil can cloud the test mixture and make it hard to see the color of the indicator. The BaSO4 did not combust. Flame Test Lab (above): Matthew having fun in the Flame Test Lab! Just take a wire (platinum or nichrome), dip it in the powder and put it in the flame and see what. Toxic elements, like barium, replace nutrient minerals in enzyme binding sites. Water - Solubility - Ions. Similarly, it is asked, what color is sodium chloride in a flame test?
