Air sample from industry heavily polluted with CO2 was analyzed.In one analysis,56L of air measured at NTP was passed through a 250mL of 0.025M NaOH solution where CO2 was absorbed completely.25mL of the above solution was then treated with excess BaCl2 solution where all carbonate was precipitated as BaCO3.Solution was filtered off and filtrate required 25mL of 0.0005M HCl solution for neutralization.
Q1ppm strength of CO2(volume by volume)=_____
Q2Weight of ppt. BaCO3 obtained from 20ml of test solution=____
Q3Fraction of original NaOH(by mole) reacted with CO2=____
-
UP 0 DOWN 0 0 2
