Question

100 ml mixture of CO and CO 2 ​ mixed with 30 ml of O 2 ​ and sparked in eudiometer tube. The residual gas after treatment with aq. KOH has a volume of 10 ml which remains unchanged when treated with alkaline pyrogallol. If all the volumes are under the same conditions, point out correct options(s):

TestHub · Accepted Answer

CO + CO 2 ​ = 100 ml x + y = 100 ml CO + 2 1 ​ O 2 ​ → CO 2 ​ Initial x 30 m Final x-60 0 60 Residual gas should be CO = 10 ml ​ ⇒ x − 60 = 10 x = 70 ml CO y = 30 ml CO 2 ​ ​ absorbed CO 2 ​ = y + 60 = 90 ml
