The sodium sulfite-acid solution should be disposed of by ____________________.
Question 5 options:
1) placing it in a designated waste container inside the fume hood.
2) reacting it with potassium permanganate before placing in a designated container inside the fume hood.
3) neutralizing the solution with sodium bicarbonate before sink disposal.
4) washing out with diluted sodium bicarbonate for sink disposal.
5) washing down the drain with large amounts of water.
This has to do with lab management. I suspect your teacher told you 1). Of course, that does not end the disposal process.
To determine the correct way to dispose of the sodium sulfite-acid solution, we need to consider the properties of the solution and follow proper disposal guidelines.
Option 1) Placing it in a designated waste container inside the fume hood:
This option suggests using a designated waste container specifically designed for chemical waste and located inside a fume hood. This is a common method of disposing of hazardous chemical waste. However, we need to ensure that sodium sulfite-acid solution falls under the category of chemical waste that can be disposed of in this manner.
Option 2) Reacting it with potassium permanganate before placing it in a designated container inside the fume hood:
This option suggests reacting the solution with potassium permanganate before disposing of it. However, it is important to know why this reaction is necessary and if it is appropriate for the specific solution being referred to.
Option 3) Neutralizing the solution with sodium bicarbonate before sink disposal:
This option suggests neutralizing the solution with sodium bicarbonate before disposing of it in the sink. Neutralizing the solution is a common method for handling acidic waste. However, it is crucial to ensure that neutralizing it with sodium bicarbonate is the correct method for the sodium sulfite-acid solution.
Option 4) Washing out with diluted sodium bicarbonate for sink disposal:
This option is similar to option 3 but specifically mentions washing out the solution with diluted sodium bicarbonate. This option implies that additional dilution is necessary before disposing of the solution in the sink.
Option 5) Washing down the drain with large amounts of water:
This option suggests washing the solution down the drain with large amounts of water. However, it is important to determine if this method complies with disposal regulations and whether the sodium sulfite-acid solution can be safely disposed of in this manner.
Based on these options, the most appropriate choice for disposing of the sodium sulfite-acid solution is option 1) placing it in a designated waste container inside the fume hood. However, it is advisable to consult the specific guidelines and regulations provided by your institution or local authorities to ensure proper disposal.
