bella esperienza da proporre, grazie! non mi è chiaro però che colorazione assume il cavolo in base all’acidità o basicità delle sostanze testate, potrebbe spiegarlo?
Grazie mille
Avremo rosso nelle soluzioni più acide, viola-blu in quelle poco acide, verde nelle poco basiche, giallo nelle più basiche
