  1. Model pH u protočnom reaktoru K L q1 q2 q0 pH q sustav q pH L = NaOH jaka lužina K = CH3COOH slaba kiselina T = konstanta h = konstanta Zadatak: izvesti matematički model procesa

  2. Reakcije disocijacije k1 H20 HO-+ H+ k -1 k2 CH3COOH CH3COO - + H+ k -2 k3 NaOH OH- + Na+ k-3

  3. Bilance za ione k2 CH3COOH CH3COO - + H+ k -2 Pretpostavka: koncentracija H20 je konstantna koncentracija je uključena u koeficijent brzine disocijacije

  4. k3 NaOH OH- + Na+ k-3 Vrijedi zakon sačuvanja naboja, neutralnosti otopine! U stacionarnom stanju vrijede relacije ravnoteže:

  5. Uvedemo novu oznaku y=ukupna koncentracija kiseline Uvedemo novu oznaku x= ukupna koncentracija lužine Uvjet neutralnosti postaje:
