Description:
Sodium Hydrogensulphate is a white, crystalline and spherical shaped (beads) substance with high hygroscopic properties.
The single beads have an approximate diameter of 0,75 mm.
It is an acid salt, a so called solid acid.
Solutions of Sodium Hydrogensulphate are caustic and on metal they have a corrosive effect.
