I need to type up a lab report and my teacher wants us to find out if iron (II) sulfate (aq) is more reactive with magnesium, aluminium, or tin. Does anyone know?

Did you do the experiment ?

No. He wanted us to look it up, but I can't find anything.

Which of the metals is more reactive? Iron sulfate was made from what? What do you think the Ph would be of the aqueous solution. Go from there.
