Product Details

College Level Classic General Chemistry Experiment In this experiment, students determine the volume of one mole of hydrogen gas at standard temperature and pressure (STP). Hydrogen is generated by the reaction of a known mass of magnesium with an excess of hydrochloric acid in an inverted gas measuring tube filled with water. The volume of hydrogen collected by water displacement is measured and corrected for differences in temperature and pressure in order to calculate the molar volume of hydrogen at STP. Complete for 24 students working in pairs.
