Biology: A Functional Approach. Students' Manual
Potassium pyrogallate is unstable and must be made up immediately before the
practical session by mixing equal quantities of pyrogallol (pyrogallic acid) and
potassium hydroxide. The potassium pyrogallate thus formed must then be
covered ...

Practical Advanced Biology
The pyrogallol reacts with any potassium hydroxide still in the tube to form
potassium pyrogallate, which then absorbs the oxygen. Record the final length of
the bubble in the capillary tube. The further decrease in the length of the bubble
is due ...

The pyrogallol will react with the potassium hydroxide still in the tube forming
potassium pyrogallate which will absorb oxygen from the air sample. Wait for one
minute, then measure the length of the air column again. 5 Calculate the ...

Action of Pyrogallate of Potash on Nitrous Oxide.— Having seen it generally
stated that pyrogallate of potash had the power of absorbing free oxygen, and
thus indicating the difference between mixtures and chemical compounds, it
occurred ...

"A Note on Pyrogallate of Lead, and on Lead Salts," by W. H. Deering, was then
read by the author. After glancing at previous examinations of the lead salts of
this acid, the author described the method he had employed in preparing the salt,
...

Chemistry of Organic Bodies: Vegetables
Pyrogallate of potash crystallizes in rhomboidal tables, which are beautifully
white. This acid occasions no precipitate in barytes or strontian water. ' Nor does
it become coloured, unless oxygen be in contact with it. When persulphate of iron
is ...
This gas is oxygen as it is completely absorbed by alkaline pyrogallate solution
turning the solution brown. Hence, nitric acid contains oxygen. 4HN03 = 4N02 +
2H20 + 02 (v) H2S04 contains oxygen - Ans. When cone, sulphuric acid is ...

Alkaline Pyrogallate for Hempel and Orsat Apparatus. — To prepare pyro- gallate
solutions for Hempel and Orsat apparatus proceed as follows: 1. Potassium
Pyrogallate Solution. — Dissolve 50 g. of pure pyrogallic acid in 150 ml. of
distilled ...

Chemical treatment of drilling fluids: a colloid chemical ...
A difference between the two flocculation curves is that the lime- treated system is
only stable beyond a pyrogallate concentration of about 2 m. eq./l. . With
increasing lime content the minimum amount of pyrogallate required to obtain a
stable ...
