1. Ile gramów siarczanu(VI) miedzi (II) potrzeb do sporządzenia 300 g wodnego roztworu nasyconego w temperaturze 40oC, jeżeli rzpuszczalność tej soli w tej temperaturze wynosi 28g? 2. Oblicz roozpuszczalność azotanu(V) ołowiu(II) w temperaturze 30oC, wiedząc, że po całkowitym odparowaniu wody z 50g nasyconego roztworu tej soli w podanej temperaturze uzyskano 20g suchej soli. 3. Oblicz, ile gramów chlorku potasu można dodatkowo rozpuścić w 50 g wody po podwyższeniu temperatury z 30oC do 90oC. 4. W 52 g nasyconego roztworu o temperaturze 40oC znajduje się 32 g substancji. Oblicz jej rozpuszczalność. Na podstawie wykresów rozpuszczalności określ, jaka to substancja. Podaj jej wzór i nazwę.
