Question

What is the use of alkaline pyrogol

Answer 1

Answer:

The aquatic plant Myriophyllum spicatum produces pyrogallic acid. When in alkaline solution, it absorbs oxygen from the air, turning brown from a colourless solution. It can be used in this way to calculate the amount of oxygen in air, notably via the use of the Orsat apparatus.

Chemical formula: C6H6O3

Melting point: 131 to 134 °C (268 to 273 °F; 404 to 407 K)

Boiling point: 309 °C (588 °F; 582 K)
