After placing a penny in zinc powder and 6.0 molar sodium hydroxide it got a silvery appearance then you put it in a flame and it got a gold appearance why?
The gold appearance that you see is actually a physical characteristic of the alloy - brass. The silvery appearance is due to the zinc plate derived from the zinc powder in the NaOH solution. Heating the zinc plated penny causes to zinc plate to physically mix with the copper layer of the original penny to form the alloy, brass. The coin appears gold. Blondie 124578963
