Hydrogen in Water
The solubility of hydrogen in water has been studied by many workers. We found the experimental work of ten to be of sufficient reliability to use in the smoothing equation. In the process of fitting the data to the smoothing equation any data points which differed from the smooth equation by about two standard deviations or more were rejected.
