Co²+NaOH

When a solution of NaOH (sodium hydroxide) is added to a solution of CO2 (carbon dioxide), a chemical reaction takes place. The reaction can be represented by the following balanced chemical equation:

CO2 + 2NaOH -> Na2CO3 + H2O

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

It's important to note that this reaction happens in aqueous solution, meaning both CO2 and NaOH are dissolved in water. Also, the reaction can release heat, so it's advisable to perform this reaction in a controlled environment and with proper safety precautions.
