Please help!! This lab is preparing (2,4 pentanedionato)-iron (III) an Iron Coordination Complex. Please try to be specific and detailed, thank you!

CH183-I Iron complex NAME DATE: Post-Laboratory Assignment List 2 specific reasons why you did not obtain 100% yield 2. Explain the role of sodium acetate in the preparation of coordination complex tris(2,4- pentanedionato)iron(III) How would using 0.42 g of sodium acetate trihydrate instead of the amount called for in the procedure change the theoretical yield of coordination complex tris(24- pentanedionato)iron(III). Explain 3. Explain why, in step 11 you are instructed to wash the collected crystals with distilled water instead of methanol or water mixed with methanol? 4. Ex

As per our honor code, we will answer the first question for you, since you have not mentioned the exact question number that you wish to know.Thank you!

The term percent yield can be termed as the ratio of actual yield to that of theoretical yield. The formula is as follows: Actual yield Percent yield= -x100 Predicted or theoretical yield The yield so obtained in a given reaction is never equal to 100%. One main reason is that if the reaction will go to competition or not. Other reason may be the formation of the side products that are formed at the end of a given reaction. The yield of a given reaction can never be equal to 100% as there always occurs loss of products due to human mistakes or errors. Evaporation might take place in certain liquid solution which may affect the overall yield of the given reaction. The transfer of liquid solution from one beaker to another can also result in the loss of the liquid and not only this, the liquid can also be spilled all over during its transfer to another beaker. During filtration process, also some amount of liquid gets dissolved by the filter paper along with the precipitate due to which the amount of liquid so formed may differ. Lastly, all the reactant species may not completely take part in the given reaction due to which quantity of products that should be formed is not formed to a complete extent.
