Equation Balancing: Is HCl + Na2S202 Balanced?
- Thread starter LVB
- Start date
In summary, the conversation discusses balancing an equation involving HCl, Na2S202, NaCl, S, H20, and SO2. The person also mentions a possible mistake in using the wrong formula for sodium thiosulphate. They also mention using mass as a way to measure the rate of reaction and ask for help finding a diagram. Websites are requested for reference.

Hello lucy it looks to me like you're doing the disappearing cross reaction rate experiment.I think you have the wrong formula for sodium thiosulphate,if so it's no wonder you're having trouble balancing it.Try again with Na2S2O3

something else ...
when measuring the rate of reaction, you can use the mass one. You know were you weigh the mass of the reactants until there is a change.
Does anyone know where i can find a diagram of this? Please leave websites if that is easiest.
Thank you muchly

1. How do you balance the equation HCl + Na2S202?
To balance this equation, you need to make sure that the number of atoms of each element is equal on both sides. Start by counting the number of atoms of each element on the reactant and product side. In this case, there is 1 hydrogen (H) atom and 1 chlorine (Cl) atom on the reactant side, and 1 sodium (Na) atom, 2 sulfur (S) atoms, and 4 oxygen (O) atoms on the product side. To balance the hydrogen (H) atoms, add a coefficient of 2 in front of HCl to get 2HCl. This also balances the chlorine (Cl) atoms. To balance the oxygen (O) atoms, add a coefficient of 2 in front of Na2S202 to get 2Na2S202. This gives us a balanced equation of 2HCl + 2Na2S202 → 2NaCl + S4O6 + H2O.
2. Why is it important to balance equations?
Balancing equations is important because it ensures that the law of conservation of mass is followed. This means that the number of atoms of each element is the same on both sides of the equation. It also helps us accurately calculate the amount of reactants needed to produce a specific amount of product.
3. Can you use fractions when balancing equations?
No, fractions cannot be used when balancing equations. Coefficients in front of each compound must be whole numbers, as they represent the number of molecules present. However, you may need to use fractions when balancing redox reactions, which involve the transfer of electrons.
4. What are some tips for balancing equations?
Some tips for balancing equations include starting with the most complex molecule, balancing elements that appear only once on each side, and checking your work by counting the number of atoms of each element on both sides. You can also use trial and error to adjust the coefficients until the equation is balanced.
5. How do you know when an equation is balanced?
An equation is balanced when the number of atoms of each element is equal on both sides. You can check this by counting the number of atoms of each element on both sides of the equation. Another way to check is by calculating the total charge on each side, which should also be equal.
