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.
Distilled water typically has very low levels of dissolved oxygen due to the absence of minerals and other gases. The dissolved oxygen level can vary depending on exposure to air and temperature, but it is generally low compared to other types of 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.
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.
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.
Yes, when is dissolved (not distilled) in water or when is melted.
