Thanks for the tips and the resources man.
You me be right and my Zn have turned into a Zinc oxide crystal structure like zincite
Maybe i heated it too much... MAPP blow torch flame can reach 1300 C

Hi all !
this is my first post here...i am a hobbyist from Greece and i just discovered this forum.
for experimenting purposes i tried to melt Zn extracted from an alkaline battery.
I had read in wikipedia that Zn melting point is abou 420 degrees Celsium so i heated Zn with a MAPP blow torch that i have but instead of melting it turned more solid and it took a pale yellow color !?
Does anyone know why so ?
Thanks in advance

making sulfuric acid
in Inorganic Chemistry
Posted
sorry for digging up this old topic..
I just made my first concetrated sulfuric acid from car battery fluid.
I condacted the experiment outside but during the process and just about before the fumes turn white i sensed a weird burn in my nose and my throat and i started coughing for 5minutes.
I was 5-6m away from the boiling mixture !
Does anyone know what is the white smoke that come out when you boil H2SO4 ?
Is there a way to prevent the release of fumes into the atmosphere... by bubbling the fumes through a NaOH solution for example ?
I also threw some Copper into concentrated H2SO4 but i didnt get the blue color that you get when you add copper into HNO3.
Why so ? does anyone know ?
H2SO4 cant oxidise copper ?
