Oxalic acid generally contains double molecular crystal water, transparent crystal or white powder, no smell, acid. There are 2 types of crystal stucture:a(rhombic) and b( ). Melting point and relative density:a-189.5℃,1.900,b-182℃,1.895. oxalic acid will lose crystal water in dry air or heating up. It’s sublimated easily with the temperature of 100℃,rapidly with 125℃ and 157℃ in large quantity and began to disassemble.
