i bought sulfuric acid from Lowe's with the same description. It appears reddish, yet i dont think it is of 93%, because i did a simple test of the dehydration of sugar and the result was very poor. The reaction proceeded very slowly so i assume it is of lower concentration.

I know that Bromine liquid is volatile and easily escapes most containers. My thought is to keep it in a vial in the freezer or bellow its melting point ( 7 C ). Any other suggestions?
