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.
Alkaline-earth metal do not react with oxygen?
Alkaline-earth metals do react with oxygen, forming oxides. The reaction tends to be less vigorous compared to alkali metals, as alkaline-earth metals have a higher ionization energy. Examples of alkaline-earth metal oxides include magnesium oxide (MgO) and calcium oxide (CaO).
Do alkaline earth metals react with oxygen?
Yes, alkaline earth metals react with oxygen to form oxides. For example, magnesium reacts with oxygen to form magnesium oxide. This reaction typically results in the formation of a white or gray powder.
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.
What is the color of alkaline pyrogallol solution?
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)
Is oxygen an alkaline earth metal?
No. Oxygen is a nonmetal.
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 oxidation state of oxygen in alkaline earth metal oxides?
The oxidation state of oxygen in alkaline earth metal oxides is -2. Alkaline earth metals always have a +2 oxidation state, which means oxygen has to have a -2 oxidation state to balance the charges in the compound.
What if you had too much oxygen?
hyperventilation and your blood becomes to alkaline.

Do alkaline earth metals react with oxygen?
Yes, alkaline earth metals react with oxygen to form oxides. For example, magnesium reacts with oxygen to form magnesium oxide. This reaction typically results in the formation of a white or gray powder.
An alkaline earth metal forms a compound with oxygen with the formula?
The formula would be MO. (M representing any of the Alkaline earth metals)
Alkaline earth metals do not react with oxygen?
No, they generally do, even at room temperature.

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