SMI Criteriа 1Describe the rоles оf оbservаtion, hypothesis, аnd testing in the process of generating and modifying explanations. A chemist notices a white solid deposit on the tap water faucets in his lab, but the distilled water faucets remain free of deposit. He assumes the deposit is calcium and decides to conduct a water hardness test by reacting a 1-mL sample of each kind of water from a sink area. He adds 1 drop of calmagite and 2 drops of pH 10 buffer to each sample. Then, he adds drops of EDTA until the solutions change color from clear to blue. He repeats the test three more times. How does the procedure described help to answer the question of whether the deposits were calcium?
