Why was it necessary to weigh the iron filings accurately though the mass of copper sulfate taken was only approximately?
Answers
it is because iron is solid and can easily sublimes in aqueous copper sulphate
Answer:
The excess of copper (II) sulphate solution is to be added to the known quantity of iron. The actual reason for using extra solution is to ensure that the iron reacts completely in the reaction. After washing and drying, the metallic copper is to be weighed, and the weights will be used to determine the amount of the iron used and the amount of the copper created.
Despite the fact that the mass of copper (II) sulphate that was taken was only roughly weighed, this is the real reason it is essential to weigh the iron filings precisely.
Explanation:
Stoichiometry is the quantitative relationship in between chemical formulae. Stoichiometric principles are used to find the right equation for the reaction between iron metal and copper(II) sulphate solution here.
