Summary
editDescriptionGallium beating heart.webm |
English: The gallium beating heart is a chemistry demonstration in which a drop of gallium is made to pulsate, like a beating heart. The gallium beating heart is similar to the mercury beating heart, but gallium is much less toxic, so this demonstration may be preferable. To make this experiment I have melted piece of gallium in 20% hot sulfuric acid. Next, i am adding to the solution droplets of 5% potassium dichromate solution. A sound effect of a beating heart has been added to this video.
Polski: Bijące serce z galu to reakcja chemiczna, podczas której kropla galu pulsuje jak bijące serce. Aby przeprowadzić eksperyment, należy roztopić kawałek galu w gorącym 20% kwasie siarkowym, a następnie dodać do niego kilka kropel 5% roztworu dichromianu potasu.
Čeština: Tlukouci galliové srdce je chemická reakce, při které kapka kapalného gallia pulzuje jako bijící srdce. K provedení tohoto experimentu je třeba ponořit kousek roztaveného gallia do horké 20 % kyseliny sírové a přidat několik kapek 5 % roztoku dichromanu draselného.
Македонски: „Галиумско срце што чука“ — хемиска реакција каде парче галиум отчукува како срце. Парче галиум се топи во врела 20% сулфурна киселина со додавање на неколку капки од 5% раствор на калиум дихромат.
中文(简体):“镓心反应”是镓像心脏那样有规律跳动的演示实验,它和汞心反应类似,但是镓的毒性较小,更适合作为演示实验。镓在20%热的硫酸中熔化(并放出氢气),溶液中加有5%重铬酸钾溶液染色。心跳声另加入视频中。 |
