Ai in imagini metoda de determinare a cantitatilor de etanol si izopropanol
odata determinate cantitatile, calculam masa de apa rezultata
1mol.......................................18g
CH3-CH2-OH -> CH2=CH2 + H2O
1mol.......................................d=18g
1mol.....................................................18g
CH3-CH(OH)-CH3 -> CH2=CH-CH3 + H2O
0,2moli..................................................e=3,6g
aceasta cantitate de apa va dilua solutia de H2SO4
prin adaugarea apei, masa de acid dizolvata ramane neschimbata
md1=c1*ms1/100=78,4*80/100=62,72g acid
md1=mdf
msf=ms1+mapa=78,4+21,6=100g solutie
cf=mdf*100/msf=62,72*100/100=62,72%
