If you are talking about sulfuric acid, the equation is as follows:
H2SO4 + 2NaOH ==> Na2SO4 + 2H2O
H2SO4 + 2NaOH ==> Na2SO4 + 2H2O
The chemical formula for sulfuric acid is H2SO4, which means it contains two hydrogen atoms (H), one sulfur atom (S), and four oxygen atoms (O). The chemical formula for sodium hydroxide is NaOH, comprising one sodium atom (Na), one oxygen atom (O), and one hydrogen atom (H).
Now, let's balance the reaction equation:
H2SO4 + 2NaOH → Na2SO4 + 2H2O
In this balanced equation, the reactants are sulfuric acid and sodium hydroxide, while the products are sodium sulfate and water. To balance the equation, we ensure that the number of atoms on both sides is equal for each element.
On the left-hand side, we have two hydrogen atoms on the sulfuric acid molecule. Therefore, we need two water molecules (H2O) on the right-hand side to balance the hydrogen atoms.
The sulfur atom is already balanced with one sulfur atom on both sides. Additionally, on the left-hand side, there are four oxygen atoms in the sulfuric acid molecule. Therefore, we place a coefficient of 2 in front of the sodium hydroxide (NaOH) to have an equal number of oxygen atoms on both sides.
Finally, we balance the sodium atoms by placing a coefficient of 2 in front of the sodium sulfate (Na2SO4) on the right-hand side.
By following these steps, we can write the balanced equation for the reaction between sulfuric acid and sodium hydroxide as:
H2SO4 + 2NaOH → Na2SO4 + 2H2O
