Summary

Description
Македонски: Демонстрација на феноменот на дисконтинуиран термохромизам. Термохромизмот претставува појава при која доаѓа до повратна промена на бојата на супстанците со промена на температурата. Во овој експеримент прикажани се четири термохромни супстанци кои имаат својство на дисконтинуиран термохромизам. Промената на бојата е реска и се одвива при точно определена температура. Имено:
  • Cu2[HgI4] ја менува бојата од црвена во темно кафеава на околу 70 °С;
  • Ag2[HgI4] ја менува бојата од жолта во црвена на околу 50 °C;
  • [(CH3CH2)2NH2]2[CuCl4] ја менува бојата од зелена во кафеава на околу 50 °С; и
  • [(CH3CH2)2NH2]2[NiCl4] ја менува бојата од жолта во сина на околу 80 °С.

English: Demonstration of the phenomenon of discontinuous thermochromism. Thermochromism is a phenomenon where a substance reversibly changes its colour due to a change in temperature. Four substances that exhibit the property of discontinuous thermochromism are shown in this experiment. The colour change is sharp and is manifested at an exact temperature. Namely:
  • Cu2[HgI4] changes its colour from red to dark brown at around 70 °С;
  • Ag2[HgI4] changes its colour from yellow to red at around 50 °C;
  • [(CH3CH2)2NH2]2[CuCl4] changes its colour from green to brown at around 50 °С; and
  • [(CH3CH2)2NH2]2[NiCl4] changes its colour from yellow to blue at around 80 °С.
Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia.
