A mixture of Na₂CO₃ and NaHCO₃ liberates 448mL of CO₂ at STP, percentage of Na₂CO₃ in the mix is?
I'm having trouble with question 31, I attempted it with the given information but it's not working (second image). I checked the solution online and it seems that they are assuming that sodium carbonate doesn't decompose. Googling "sodium carbonate decomposition" shows that it does decompose to Na₂O and CO₂. The answer is given as (b) 16%.

to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.so nahco3 breaks down to na2co3 at 80 deg C (along with h2o and co2)
na2co3 is much higher
ideally the q should give temperature
Ohh
Thank you Sir
Is this (temperature at which it decomposes) learnt in other chapters?
not sure if it is in ncert, my lines are blurred right now cos jee adv is coming up
jd lee has all this
something like 500 odd deg tha
