Two simple physical methods are used to identify iron powder and graphite powderHurry up, you need it urgently! Thank you
A magnet attracts iron powder... Take the same volume of two substances, respectively, in the hands of weighing, the heavier iron powder
First, with a magnet, you can use a magnet, can be sucked into the iron powder.Two, put in the water, floating above the sink in the bottom of the graphite powder, iron powder
That's simple. Just use a magnet. Iron is stronger than graphite. Test the conductivity, or measure the density, because the two substances are black and the color doesn't work. I wish you progress in your studies
The first kind, with magnet, can be sucked up is iron powder. Second kinds, high temperature melting, the first melting is iron powder
