n1 moli maltoza C12H22O11 + 2Cu(OH)2 = acid + Cu2O↓ + H2O
n2 moli zaharoza:
n1Cu2O = n1 = 2,88/144 = 0,02 moli maltoza
maltoza + H2O = 2 glucoza
zaharoza + H2O = glucoza + fructoza
glucoza + 2Cu(OH)2 = acid gluconic + Cu2O↓ + H2O
n2Cu2O = 2n1 + n2 = 8,64/144 = 0,06 moli 2x0,02 + n2 = 0,06
n2 = 0,02moli zaharoza
a) nM/nZ = 0,02/0,02 = 1/1
( 0,02+0,02)342 + m apa = 103,68 m apa = = 103,68 - 13,68 = 90 g
b) dupa hidroliza : n glucoza = 2n1 + n2 = 0,06 moli n fructoza = n2 = 0,02 moli
nG/nF = 3/1
