The shaker containing the yellow solution of the potassium salt of cobalt tetracarbonyl hydride is connected with the nitric oxide reservoir (ssmthesis 37), swept with nitric oxide, and the shaking action started. Soon the solution turns red, and after a time a yellow vapor appears above the solution. From this point on, the solution is swept slowly with nitric oxide at the rate of 2 l./hour for 5 hours, with the... 

The procedure for the preparation of the potassium salt of cobalt tetracarbonyl hydride is carried out as already described. Because acidification of this solution liberates not only the hydride but also 700 ml. of carbon dioxide, the operation cannot be carried out in the shaker owing to excessive foaming.
