What is alkaline pyrogallol?
It is a solution formed by the combination of pyrogallic acid and KOH (potassium hydroxide).
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 gas is absobed by the alkaline pyrogallol?
oxygen (O2)
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.
What is the color of pH strip when the water has a 9.5 pH level?
First of all it is NOT water at this pH level. It is an ALKALINE Solution. With a pH = 9.5 the colourt would be blue.

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

When a tip of litmus paper is dipped into an alkaline solution the paper turns what color?
It stays blue.
What is alkaline solutions?
when pH of a solution is in the range of 7-14, the solution is said to be alkaline solution.
What Alkaline solution starting with letter l?
alkaline solution beginning with L
