I apologize but there seems to be a mistake in the chemical formula you mentioned. Zn2(OH)3SO4 is not a valid chemical substance. Perhaps you were thinking of Zn(OH)2 (zinc hydroxide) or ZnSO4 (zinc sulfate).
If you are interested in zinc sulfate (ZnSO4), it is a white, odorless solid that is highly soluble in water. It is commonly used in agriculture as a micronutrient fertilizer. Zinc sulfate can be prepared through the reaction of zinc with sulfuric acid or from the reaction of zinc, copper and sulfuric acid.
On the other hand, Zn(OH)2 is a white solid that is insoluble in water but soluble in acids or dilute bases. It can be prepared through the reaction of zinc with water or between zinc and sodium hydroxide.
I hope this information is helpful to you.
