Co²+NaOH

The reaction of CO2 (carbon dioxide) with NaOH (sodium hydroxide) can be represented by the following balanced chemical equation:

CO2 + 2NaOH -> Na2CO3 + H2O

In this reaction, carbon dioxide reacts with sodium hydroxide to form sodium carbonate (Na2CO3) and water (H2O).

Please note that this is a simplified equation and in actuality, the reaction between CO2 and NaOH is a bit more complex as it involves the formation of intermediate bicarbonate ions (HCO3-) before the final formation of sodium carbonate.
