Three beakers contain different substances; you need to find which of the three is sodium hydroxide. you use china rose water to test. Identify which beaker had sodium hydroxide. Give reason.
Three beakers labeled A, B, C, containing liquids of different colors. Beaker A is red, Beaker B is pink/magenta, Beaker C is green.]
China rose indicator turns green in basic solutions. Sodium hydroxide is a strong base. Therefore, the beaker that contains sodium hydroxide will show a green color when tested with China rose water. Based on the image, <b>Beaker C</b> has the green solution, indicating it contains sodium hydroxide. Beaker A (red) would be acidic, and Beaker B (pink/magenta) would be neutral or very weakly acidic/basic.
