Transcript of lastnosti ionskih in molekulskih kristalov

Lastnosti
ionskih in
molekulskih
kristalov tališsce topnost v polarnem topilu

v vodi v nepolarnem topilu

v bencinu visoko taliscšče nad 100°C

ionski kristali nizko taliscšče do 100°C

molekulski kristali prevodnost
električnega toka dobra prevodnost
ionskih kristalov
v vodni raztopini molekulski kristali v vodni raztopini
niso prevodni http://www.kii3.ntf.uni-lj.si/e-kemija/file.php/1/output/ravnotezje/index.html http://www.kii3.ntf.uni-lj.si/e-kemija/file.php/1/output/ravnotezje/index.html http://www.kii3.ntf.uni-lj.si/e-kemija/file.php/1/output/lastnosti_kov/index.html http://www.osbos.si/e-kemija/e-gradivo/4-sklop/temperatura_talia_in_vrelia2.html http://www.osbos.si/e-kemija/e-gradivo/4-sklop/topnost_in_pravilo_topnosti.html sladkor ali sol

Uporabljene snovi uvrščamo med molekulske, ionske in kovinske kristale. Odgovori na vprašanje. Poglejmo polarnost molekul http://phet.colorado.edu/sims/sugar-and-salt-solutions/sugar-and-salt-solutions_en.jnlp http://phet.colorado.edu/sims/molecule-polarity/molecule-polarity_en.jnlp Poglejmo animacijo topnosti snovi Zgradba snovi-kristali http://www.osbos.si/e-kemija/e-gradivo/4-sklop/zgradba_trdnih_snovi__kristali.html
