Ce |
KBrO3 CH2(COOH)2 MnSO4·xH2O H2SO4 (dilute) Ce(SO4)2·xH2O |
Oscillating reaction. The classical Bhelousov-Zhabotinsky reaction. A well-known classical, but very beautiful, experiment. |

Nd |
Nd2O3 H2SO4 (dilute) HNO3 (dilute) HCl (dilute, colorless grade) HCl (30+ %, reagent grade) |
Narrow absorption bands of neodymium ions. In this experiment it is shown that the appearance of a solution of neodymium salts strongly depends on the type of light source, used for viewing the solution. The effect is really striking! |

Pr |
Pr (pure metal) PrCl3·xH2O HCl (30%) |
Praseodymium chemistry. Praseodymium is dissolved in hydrochloric acid and some experiments are done with the resulting metal salt solution. |
