how to determine the molarity of iron (II) acetate solution? design an experiment. Would it be possible to determine the molarity be immersing a material in it then applying another substance ? confused because there is no way to know liters of solution.
would it be okay to react it with something such as lead or silver?? then determine the mass of that compared to mass of iron? or would it need to be reacted with something like OH?
Why can't the volume be measured? It's too large or irregular shaped vessel or something like that. In that case take an aliquot; e.g. a 50 mL or 100 mL aliquot with a pipet. Then titrate the Fe(II) with a standard KMnO4 solution.
IronII acetate solution? Isn't ironII acetate insoluble in water? I bet it is Iron(II) acetate tetrahydrate dissolved in the solution.
You can determine the iron by using test strips, cheaply available. From the color chart, you know the amount of iron, then you can use that to figure amount of iron in a liter of solution, and from that, calcuate the molarity.

To determine the molarity of an iron (II) acetate solution, you can conduct a titration experiment. Titration involves adding a known volume of a reagent (titrant) of known concentration to react with the substance you want to analyze (analyte). In this case, you would use a suitable titrant, such as a standard solution of sodium hydroxide (NaOH), to react with the iron (II) acetate solution.
Here's a step-by-step procedure for designing the experiment to determine the molarity of iron (II) acetate solution:
1. Obtain a known volume of the iron (II) acetate solution. Let's say you take 25 mL. Note the volume accurately.
2. Set up the titration apparatus. This typically involves using a burette to deliver the titrant (NaOH), a suitable indicator to signal the endpoint of the reaction, and a conical flask to hold the iron (II) acetate solution.
3. Add a few drops of an indicator that can detect the endpoint of the titration process. For example, phenolphthalein or methyl orange can be suitable indicators.
4. Fill the burette with the standardized solution of NaOH. Note the initial volume of the titrant accurately.
5. Start the titration by slowly adding NaOH from the burette into the flask containing the iron (II) acetate solution, while continuously swirling the flask. The indicator will change color at the endpoint, indicating that the reaction is complete.
6. Record the final volume reading on the burette when the color change occurs. Make sure to note the volume accurately.
Now, let's address your second question. You mentioned immersing a material and using another substance to determine the molarity. Unfortunately, this approach would not be suitable for determining the molarity of a solution accurately unless you know the volume of the solution. Volume is a vital parameter for molarity calculations since it represents the amount of solute dissolved in the solution per liter (mol/L).
In summary, designing a titration experiment is a reliable method to determine the molarity of an iron (II) acetate solution accurately. Immersing a material and applying another substance would not be sufficient to determine molarity without knowing the volume of the solution.
