To Conduct Demonstration Lift the balloons one at a time so that the Mg falls into the HCl in each flask. Swirl to speed up reaction. Make sure all the Mg is emptied out of the balloon. Each flask ...

Magnesium metal is dissolved in HCl in 500mL Florence flasks covered with balloons. The moles of each reagent are changed in each flask in order to demonstrate the limiting reagent concept. In flasks ...

Effervescence is an indicator of a chemical reaction taking place. Watch this video to see how magnesium and dilute hydrochloric acid react to produce bubbles of hydrogen gas. Every chemical ...
