So I will be performing plenty of acid leaches during my current project, which is followed by an evaporation step. The acids to be evaporated are aqua regia and concentrated HNO3, and volumes are 50-100 mL per occasion.
To prevent damage of the fume hood ducts, my supervisor suggests keeping a beaker of concentrated ammonia stirring in the fume hood to neutralise the acid vapours coming off the hot acid, and taping some wet pH paper inside to follow the process. To me, this sounds quite silly, and I would feel a lot more comfortable with a more proper setup. Say performing the evaporation in a round bottom flask or E-flask, and connecting a cooler and leading the condensate into a basic solution for neutralisation.
What do you guys think? Is the suggestion by my supervisor enough, or do you have any suggestions for a proper setup?
