Sulfur dioxide gas is bubbled through sodium hydroxide solution

Write the balanced formula equation for this reaction

NaOH + SO2 ==> Na2SO3 + H2O

You balance it.

2NaOH + SO2---> Na2SO3 + H2O

To write a balanced formula equation for the reaction between sulfur dioxide gas (SO2) and sodium hydroxide solution (NaOH), we need to first identify the products of the reaction.

When sulfur dioxide (SO2) reacts with sodium hydroxide (NaOH), it undergoes a neutralization reaction, resulting in the formation of sodium sulfite (Na2SO3) and water (H2O).

The balanced formula equation for this reaction can be written as follows:

SO2 + 2NaOH → Na2SO3 + H2O

In this equation, the number of atoms of each element on both sides of the equation is balanced, indicating a balanced formula equation.
