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)

What gas is absobed by the alkaline pyrogallol?

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.


What is alkaline pyrogallol?

Alkaline pyrogallol is a chemical used in the Biuret protein assay method to determine protein concentration in a sample. It reacts with proteins to produce a color change which can be quantified to measure the protein concentration.


What is the element that absorbs oxygen?

Pyrogallol,when in alkaline solution, it absorbs oxygen from the air, turning brown from a colourless solution. or simply none


Why Alkaline pyrogallol absorbs oxygen when used on germinataing seeds?

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.


Alkaline pyrogallol absorbs oxygen when used on germinataing seeds. True or false?

True ^.^


What is the color of litmuspaper in a alkaline supension?

Itmus becomes blue in alkaline suspension or solution.


What color does blue litmus turn when dipped in an alkaline solution?

The solution is alkaline, because litmus paper remains blue in alkaline solutions and turns red in acidic solutions.


When neutral litmus solution is added to alkaline solution?

When neutral litmus solution is added to an alkaline solution, the litmus solution will turn blue. This change in color indicates that the solution is basic or alkaline in nature. Litmus paper is commonly used as an indicator to determine the acidity or alkalinity of a solution.


What color does paper turn when dipped into alkaline solution?

Blue litmus turns red.


How do you determine Carbon Monoxide Carbon Dioxide Oxygen and Hydrogen contents in a sample of producer gas by Orsat Apparatus?

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.


When a tip of litmus paper is dipped into an alkaline solution the paper turns what color?

It stays blue.


What color does blue litmus paper turn when dipped in an alkaline solution?

Red, because litmus paper remains blue in alkaline solutions and turns red in acidic solutions.
