Which one out of the NaOH and KOH, is a better absorber of CO2 ? (a) NaOH (b) KOH (c) both absorb CO2 equally (d) can not be predicted. Give explanation.no link

Dear Student

Option B is correct.

KOH is a strong base and CO2  is an acidic oxide. So, it will react to form salt and water.
KOH + CO2  → K2CO3 + H2O

This is the reason why KOH is a stronger base than NaOH.
