It is a solution formed by the combination of pyrogallic acid and KOH (potassium hydroxide).
Oxygen gas is absorbed by alkaline pyrogallol. The pyrogallol reacts with oxygen to form a compound called purpurogallin, which causes the solution to turn brown.
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.
It's colourless. When it absorbs oxygen from the air, it turns purple. It can be used in this way to calculate the amount of oxygen in air. colourless → + oxygen → purple (just an example, not a proper format)
The IUPAC name of pyrogallol is 1,2,3-trihydroxybenzene.
In an Orsat apparatus, Carbon Monoxide is absorbed by a solution of potassium hydroxide, Carbon Dioxide is absorbed by a solution of potassium hydroxide and pyrogallol, and Oxygen is absorbed by a solution of alkaline pyrogallol. Hydrogen is typically calculated by the difference in the volume of the sample gas before and after the absorption process. By measuring the volume changes in the different absorption bulbs, you can calculate the percentages of each gas component in the sample of producer gas.

Pyrogallol,when in alkaline solution, it absorbs oxygen from the air, turning brown from a colourless solution. or simply none
The pyrogallol method involves using pyrogallol to remove oxygen from a closed system. Pyrogallol reacts with oxygen, creating a vacuum that can help create anaerobic conditions. This method is commonly used in laboratories when working with oxygen-sensitive materials or to create anaerobic environments for certain experiments.
The IUPAC name of pyrogallol is 1,2,3-trihydroxybenzene.
its answer is oxygen because pyrogallol absorbs oxygen so used to measure amount of oxygen in any substance

yes toothpaste is an alkaline because the alkaline overpowers the acid in the toothpaste
Hominy is alkaline, with a pH above 7.
