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.
Even boiled distilled water will still have oxygen, but the oxygen will not be in elemental form as a dissolved gas.
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.
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.
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.
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.
It should be 0.
Even boiled distilled water will still have oxygen, but the oxygen will not be in elemental form as a dissolved gas.
The dissolved oxygen in the water reacts with the nail to form rust.
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.
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.
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.
The oxygen dissolved in water is a measure of dissolved oxygen (DO).
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.
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.
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.
Yes, when is dissolved (not distilled) in water or when is melted.
