Explain the following with the help of Henry’s law : (i) Bends (ii) Anoxia

State Henry's law. Calculate the mole fraction of \(CO_2\) in water at \(298\,K\) under \(760\,mm\,Hg\). (Given : \(K_H\) for \(CO_2\) in \(H_2O\) at \(298\,K = 1.25 \times 10^6\,mm\,Hg\))

The boiling point of an azeotropic mixture of water and nitric acid is more than that of pure water and nitric acid. The mixture shows :
