Your second equation as you showed is correct. Not sure what confuses you. Did you check the electrons count? I did not check carefully myself, but your "reaction 2" is the same (except for typesetting) as shown in the wikipedia article for "thiosulfate". Atoms there seem to balance and half-reaction electrons seem to be right.Kolika28 said:Cl2(g) + 2I–(aq) -->I2(aq) + 2Cl–(aq) (reaction 1)
2S2O3^(2-)(aq) + I2(aq) --> S4O6(2-)(aq) + 2I–(aq) (reaction 2)
Why isn't n(I2)(reaction 2)=2n(S2O3^(2-))(reaction 2). I don't see why this is wrong.
Stoichiometry is the study of the quantitative relationships between reactants and products in a chemical reaction. It involves using balanced chemical equations to determine the amount of each substance needed to produce a certain amount of product.
The purpose of investigating the stoichiometry of reactions 1 & 2 is to understand the specific ratios of reactants and products in these reactions. This information is important for predicting the amount of product that will be formed and for optimizing the reaction conditions.
The stoichiometry of a reaction can be determined by balancing the chemical equation and using the coefficients to determine the mole ratios of reactants and products. This allows for the calculation of the amount of each substance needed or produced in the reaction.
The stoichiometry of a reaction can be affected by changes in temperature, pressure, and concentration of reactants. The presence of catalysts or inhibitors can also alter the stoichiometry of a reaction.
The stoichiometry of a reaction is used in various practical applications such as in the production of medicines, fuels, and other industrial products. It is also used in environmental monitoring and in understanding the chemistry of biological processes.
