Is sodium bisulfite soluble in water?

WaterSodium bisulfite / Soluble inWater is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, despite providing neither food, energy, nor organic micronutrients. Wikipedia

What happens when sodium bisulfite reacts with water?

It is known that sodium metabisulfite can react with acids and water, releasing toxic sulfur dioxide (SO2) gas. In addition, SO2 gas reacts with respiratory tissue forming sulfureous acid, and inducing a pulmonary reaction causing hypoxemia.

What can I use instead of sodium bisulfate?

6 hoursIt takes time for sodium bisulfate to start working. It is an excellent solution but is not instantaneous. It may take a minimum of 6 hours to get the job done, so be patient — and stay out of the water. Once your time is up, you will want to retest the water's pH levels using your testing kit.

How do you make sodium bisulfite from sodium sulfite?
