    Ethanolamine, C2H7NO, is a clear, viscous, hygroscopic liquid with an ammonia-like odor. It is used to remove CO2 and H2S from natural gas but it is also found in polishes, hair waving solutions, and in emulsifiers (often in pharmaceuticals). Overexposure to this compound can cause irritation to the eyes, skin and respiratory system as well as lethargy. If a 0.25M solution of this compound is found to be 125 % ionized, determine the Kb and the Ka for this substance....
