liczba moli Na2CO3 = 0,1 dm3 * 0,001 mol/dm3 = 0,0001 mol
liczba moli BeSO4 = 0,2 dm3 * 0,01 mol/dm3 = 0,002 mol
n(Na2CO3) = n(CO32-) = 0,0001 mol
c(CO32-) = 0,0001 mol / 0,3 dm3 = 0,000333 mol/dm3
n(BeSO4) = n(Be2+) = 0,002 mol
c(Be2+) = 0,002 mol / 0,3 dm3 = 0,00667 mol/dm3
[Be2+][CO32-] = 0,000333 * 0,00667 = 2,2 *10^(-6) > Ks (BeCO3),
a zatem osad BeCO3 wytraci sie.
