Hello fellow wanderers , its been a long time since i posted. Hope you guys are good , healthy and in love.

I have some fumaric acid that a bought and it has an expiration date. I still need to do some works with it but it expires shortly.

So i was thinking , should i put the acid in the freezer to keep it good for for some more time ??
Also what would happen if acid expires , would it become weaker or what ??

Thank you guys for reading this and for your time.
Work you doing here is priceless.

Everybody be well always !!!!!!!!!!!

Your fumaric acid will be fine if you store it in a closed jar. I bet it will still be fine in a hundred years. The expiration date is either some braindead legal requirement or a sales ploy. Table salt also has an expiry date.

Hey pitubo , thank you for taking your time and answering my question . I really appreciate it !!!
