In summary, after conducting the penny to gold demo using zinc powder and sodium hydroxide, the leftover substance is a whiteish grey solid, which is believed to be sodium zincate. With approximately 17g of this substance, it is important to dispose of it properly according to local waste management regulations. This may involve putting it in the trash or taking it to a hazardous waste disposal facility. It is important to check with your local authority for the best disposal option.

I just did the penny to gold demo which uses zinc powder and sodium hydroxide. I used 200ml 3M NaOH, and 10g of Zinc (did it twice with 100ml and 5g each time). Now that its over, I have a whitish grey solid leftover which I am assuming is sodium zincate Na2[Zn(OH)4]. I can't seem to find any information about sodium zincate and was wondering how to dispose of it. I have about 17g of this substance total.

I'm concerned because during this experiment a chunk of wet zinc powder fell onto some paper and burnt a small cigarette sized hole in it. Thanks.
