I've been searching for good sources of SN and I came across this website. They're selling two kinds of SN namely AR and LR. I googled it and found out that AR is the one with the highest purity and it stands for ANALYTICAL REAGENT. I need help choosing it. They're selling 500 grams which is the minimum quantity. Do you guys think it's genuine? I need some help. Thanks in advance.
