A student preparing to do this experiment filled the 150-mL beaker with a colorless liquid that was supposed to be water. Later, the student feared that 1.0M HCl had been used mistakenly instead of water. (a) Explain how the student could use a tiny piece of Mg to determine whether the solution in the beaker was 1.0M HCI or water. What, specifically, would the student observe if the beaker contained HCI solution? If the beaker contained water? (b) The student concluded that the beaker contained HCl solution, which is toxic and corrosive. Suggest a procedure the student could follow, using reagents available for this experiment, to make the solution safe enough to be poured into the drain, diluting with a large amount of running water. (c) Describe any safety precautions the student should take in carrying out the procedure mentioned in.
