In una quinta provetta abbiamo messo il nitrato di argento AgNO3, già liquido. Infine, abbiamo fatto avvenire delle reazioni tra la soluzione di NaCl e AgNO3, le soluzioni di Pb(NO3)2 e K2CrO4 e quelle di Pb(NO3)2 e K2Cr2O7. Le sostanze hanno cambiato colore: la prima è diventata bianca e le ultime due gialle. ]]> 2016-04-26 10:23:01 UTC https://padlet.com/giulianan/sali/wish/107740140 giulianan https://padlet.com/giulianan/sali/wish/107741893 Durante le reazioni, i sali si sono dissociati creandone poi altri.]]> 2016-04-26 10:33:37 UTC https://padlet.com/giulianan/sali/wish/107741893 giulianan https://padlet.com/giulianan/sali/wish/107742082 Pb(NO3)2
