It should be zero. We can use as DO standard solution instead of 2.0 M sodium sulphite (because 2.0 M Na2SO3 DO is zero). Refer to the following link below.

Will boiled distilled water no longer have oxygen?

Even boiled distilled water will still have oxygen, but the oxygen will not be in elemental form as a dissolved gas.


Iron nail rust quicker in tap or distilled water?

If both t etap water and the distilled water are open to the air and both have dissolved oxygen then the iron nail will rust faster in tap water. Rusting requires dissolved oxygen and goes faster if there are dissolved salts.


What is the pH level of sodium acetate and distilled water?

Sodium acetate is a basic salt, so when dissolved in water it will slightly increase the pH above 7. Distilled water has a neutral pH of 7.


What is the dissolved oxygen level of pond water?

The dissolved oxygen level in pond water can vary depending on factors such as temperature, aeration, and biological activity. Generally, a healthy pond should have dissolved oxygen levels above 5 mg/L to support aquatic life. Testing the water with a dissolved oxygen probe or chemical test kit can provide an accurate measurement.


What factors cause the level of dissolved oxygen in water?

The level of dissolved oxygen in water can be influenced by temperature (warmer water holds less oxygen), water flow and turbulence (increased mixing allows for more oxygen absorption), and the presence of aquatic plants and algae (which can produce oxygen through photosynthesis). Pollutants like nutrients and organic matter can also lower dissolved oxygen levels by promoting algal blooms and microbial activity that deplete oxygen.

What makes a nail rust in distilled water?

The dissolved oxygen in the water reacts with the nail to form rust.


Is iron rust in distilled water?

Yes, provided there is oxygen dissolved, which will be the case if the distilled water is open to the air, a rusting reaction will take place. It will be slow. The reaction is much quicker when there are dissolved salts.


What makes iron rusts in distilled water?

An iron nail will rust slowly in distilled water when that water has dissolved oxygen. If you get rid of the oxygen by boiling and keep it from getting back in then the iron nail will not rust at all.

What is the oxygen dissolved in water is a?

The oxygen dissolved in water is a measure of dissolved oxygen (DO).


What does the level of dissolved oxygen go down after sunset?

The level of dissolved oxygen in water can decrease after sunset due to the lack of photosynthesis by aquatic plants. Without sunlight, plants stop producing oxygen through photosynthesis, while organisms in the water continue to consume oxygen through respiration, leading to a decrease in dissolved oxygen levels.


What is the pH level of sodium acetate and distilled water?

Sodium acetate is a basic salt, so when dissolved in water it will slightly increase the pH above 7. Distilled water has a neutral pH of 7.


What is the relationship between distilled water and salty water?

Both are made up of 2 hydrogen atoms bonded with an oxygen atom. The difference is that distilled water is pure water, saline or salty water has sodium chloride dissolved into the solution.


Is sodium chloride a strong electrolyte when distilled in water?

Yes, when is dissolved (not distilled) in water or when is melted.
