Chemical Properties of Zinc Powder:
(1) Zinc powder is insoluble in water but soluble in acid, alkali and ammonia water.
(2) Zinc powder has strong performance of reducing action and it can releases hydrogen in the reaction with acid or alkali.
(3) Zinc powder is easy to form lumps due to dampness. It is easy to produce white basic carbonate on its surface in the wet air, but stable in the dry air.
(4) Zinc powder bruning issue of blue green flame, accompanied by combustion of zinc oxide.
