- Aufgabe: Salze-72
100 Grammi NaCl dissolvere La in 400 ml Acqua. Calcolo di cui: che LProdotto vegetale di: NaCl
Lösung: Es Applicabile:
— 1·NaCl ⇄ 1·Na+ + 1·Cl–
— c(NaCl) = c(Na+) = c(Cl–)
— Lp(NaCl) = c(Na+)·c(Cl–)
— c = n/V = m/M/V
— c(NaCl) = 100g/58.5 g/mol / 0.4 l = 4.27 mol/l
— Lp(NaCl) = 4.27 mol/l · 4.27 mol/l = 18.26 mol2/l2
