Sunil,

We need a lot more information to answer this question. For example, at what temperature will you store it? at what concentration? how long do you plan on storing it before you use it and make a new batch?

I wouldn't recommend it, just because there is a risk of localized corrosion if there are small imperfections in the tank interface with the acid. I would be more comfortable with a polymer based storage tank. I use those myself and they've worked great for me. Good luck.

I belong to jewellery industry. We use nitric and store in glass bottles. It is used for gold refining. You can contact a refiner and see how it is stored. I am talking about not much powerful concentration used in labs.
