d=m/V =) m= d×V=1.183×200 = 236.6 g soluție acid 36% = ms
md = ms×100/C= 236.6×100/36 = 85.176 g acid dizolvat =85.176/ 98 moli = 0.869 moli acid
Pentru NaOH:
Cm=n/Vs=) n=Cm×Vs= 0.5×0.4 = 0.2 moli NaOH
2NaOH + H2SO4 = Na2SO4 + 2H2O
M Na2SO4 = 142 g/mol
98g H2SO4 ....142g sare
85.176..............x=123.418g sare
Concentratia molara H2SO4: Cm= n/Vs= 0.869/0.2 = 4.345 moli/litru
