In salt analysis 3rd group basic radicals (Al3+, Fe3+etc) are detected by adding NH4Cl to the salt solution and then NH4OH. 3rd group radicals are precipitated as hydroxide. In this process
At 1000 C, the equilibrium constant for the reaction of carbon monoxide and oxygen to produce carbon dioxide is very large (Kc= 1.2 x 1022). When the reaction is at equilibrium the
