The Hydrobichromate, (C 1 , s l I 1; N) L , I L.( 'rJ ) r . — To the base dissolved 

 in dilute sulphuric arid, some crystals of potassium bichromate were 

 added and the mixture gently heated. On cooling the solution, the 

 hydrobichromate crystallized out in large brilliant yellow prismatic 

 plates, and upon reerystallization it was soon obtained pure. It is 

 sparingly soluble in cold, but easily in hot water. When heated, it 

 deflagrates and leaves a green oxide Cr 2 3 . The crystals of the 

 hydrohichromate, after being dried over sulphuric acid, were analysed : 



I. 0.3557 gram the salt gave, on combustion, 0.1853 gram H 2 

 and 0.5491 gram C0 2 . 



II. 0.2504 gram the salt, when ignited, gave 0.0831 gram Cr 2 3 .
