What color is SN.

[Challu]

It came pure white. I've seen threads saying it should be yellowish?

Hey, I have my SN from IC right now and for me, the SN crystals are a slightly yellowish color.
This is from wikipedia " It is a white to slightly yellowish crystalline powder that is very soluble in water and is hygroscopic.", so it could be white
Though sodium nitrAte is a pure white crystal, so if you want to be sure, you can use an aquarium testing strip

I confirmed it is yellowish. I hadn't looked at correctly when I got it 3 months ago.
I also recieved it from IC.
