Answer to Question #232375 in Inorganic Chemistry for Kinno

Question

pH of water sample is 7.0 and concentration of bicarbonate is 53mg/L. Determine the total concentration of Carbonate system.(in mole/litter)
H2CO3 ........ H+ + HCO3-. Pk1 5.6
HCO3-.......... H+ CO2(2-) pk2 8.4

Answer 1

7.0 = x(5.6 + 8.4)/53

7 =x 14/53

53× 7 = 14x

371 = 14x

X = 26.5 mol/L
