The stability of hydrophobic sol is due to the charge on the colloidal particle.when charge is removed from it by the addition of suitable electrolyte.then particle come nearer to each other and they will coagulate and settle down.

Why peepal tree releases oxygen at both day and night??

Posted by Yash Agarwal 7 years, 3 months ago

CBSE > Class 12 > Chemistry

1 answers

Yogita Ingle 7 years, 3 months ago

During the day, in presence of sunlight, the plants use up the CO₂ and release O₂ in the process of photosynthesis. But during night, plants won’t perform photosynthesis so they are unable to use the CO₂ and this further leads to increase in the proportion of CO₂ in the air. During night the trees breathe in oxygen and release CO₂ . If one sleeps under the trees, the amount of increased CO₂in the air around will certainly affect the health. So it is inadvisable to sleep under trees during night. He suffers from suffocation. He feels excess weight on his chest. For this reason, some rural people imagine and fear that ghosts would come and sit on their chests if they sleep under Peepal or Banyan trees.

Yogita Ingle 7 years, 3 months ago

Role of NaCN in the extraction of silver (Ag) is to do the leaching of Ag ore in the presence of air from which the silver is obtained later by replacement.

4Ag + 8CN^- + 2H₂O + O₂ → 4 [Ag(CN)₂^-] + 4OH^-
