Reagents and equip­ment: * plas­ticine; * bak­ing soda (10 g); * red food col­or­ing; * liq­uid soap (10 ml); * 9% so­lu­tion of acetic acid (100ml); * spoon. Step-by-step in­struc­tions Make a vol­cano with plas­ticine and pour bak­ing soda into the “crater”. Then add a few drops of food col­or­ing and liq­uid soap. Stir thor­ough­ly. Then add acetic acid to the mix­ture. Watch the vol­cano erupt! Pro­cess­es de­scrip­tion Bak­ing soda is sodi­um bi­car­bon­ate. It re­acts with acetic acid with the re­lease of car­bon diox­ide. The gas makes the liq­uid soap froth, and the vol­cano erupts! NaH­CO₃ + CH₃­COOH = CH₃­COONa + CO₂ + H₂O
