Generally, before you try to make an aqueous solution of a salt (basically, dissolving them), you should check against a solubility table. But that's the simplest way. HCN + NH4OH H2O + NH4CN, NH4CN To determine whether salt is acidic or basic must look at ka vs kb values of HCN VS NH4OH and whichever one is greater will determine salt type. Let's clear up people's false perspective on radiology myths and give them a clear thinking about radiology. On the other hand, the CH3NH3CN molecule present in the blood is generally neutral because it allows optimal transport of nutrients and oxygen throughout the body.
