This is because the absorption of sodium is an energy-dependent process. Without an adequate oxygen supply, the cell will not have sufficient ATP available to absorb the sodium.
Do you breathe metal? Oxygen is a gas, not metal.

Oxygen reacts with the molecule sodium thioglycollate. If this is in a broth, the broth will end up having a gradient of available oxygen in it, with lower and lower levels of oxygen the farther down you go to the bottom. As for the brewer's agar, the sodium thioglycollate isn't enough to reduce oxygen levels to a low enough percentage to allow species like Closteridium sporogenes (for example) to grow. These plates must be kept in an airtight chamber with all oxygen somehow removed from it (most commonly a gas pack system that captures oxygen from the air). Hope this helps.
It is a general term for the transport of dissoolved material in plants this can be glucose, oxygen or other minerals such as sodium/potassium hope this helps
A table salt substitute such as potassium chloride may be effective.
alkaline pyrogallol will still absorb oxygen with or without germinating seeds. There is a common chemistry experiment were the percentage of oxygen is determined by mixing pyrogallol and base sodium hydroxide which forms the alkaline pyrogallol. Don't ask me why and how the mechanism is still not clear to me.
Sodium chloride absorb water and microorganisms die without water.
2NaOH + CO2 ---> Na2CO3 + H2O sodium hydroxide absorb carbon dioxide from moist air and turns sticky.
Sodium and oxygen produce sodium oxide, Na2O.
Sodium chloride is hygroscopic, absorb water.
Sodium + Oxygen = Sodium oxide: 4Na + O2 = 2Na2O
Sodium chloride absorb water and microorganisms are killed; they cannot live without water.
Sodium (Na), oxygen (O), and hydrogen (H). The formula is NaOH. Sodium (Na), oxygen (O), and hydrogen (H). The formula is NaOH.

Sodium hydroxide is use to absorb carbon dioxide.
