Storage of HCL and NaOH - (Dec/09/2010 )

Hi everyone,
I am making 1 N HCl and 10 N NaOH and am wondering what is the best way of storing them. Can I store them in PET plastic bottles? Does it matter if the bottle is rigid or flexible?


For NaOH I'd avoid glass bottles, but use a PE-bottle. For HCl too, but also a glass bottle (e.g. the standard Schott) is okay.
About PET I've no idea...


And you should be aware that NaOH has limited shelf life, since it absorbs CO2 from the air and gradually converts to sodium carbonate.
