loss, 0.205 moles of iron (III) potassium oxalate should remain. After converting 0.205 moles of iron oxalate and potassium trihydrate to grams, the yield is approximately 101 grams. 4. 5.00 g of ammonium (II) hexahydrate, 1.68 g of ammonium sulfate, 1.25 g of sulfuric acid and 0.919 g of water are obtained. a. [Cr(NH_3 )_4 Cl_2]Cl(s) will ionise to [Cr(NH_3 )_4 Cl_2 ]^+ (aq)andCl^- (aq)ions. b. K_2 [PtCl_4](s)will ionise to2K^+ (aq)and[PtCl_4 ]^- (aq)ions. c. [Co(en)_3](NO_3 )_3 (s)will ionise into[Co(en)_3 ]^(3+) (aq)and3(NO_3 )^(3-) (aq) _ions. Part 2 Lab Questions When a permanganate falls on the burette wall, the volume recorded to reach the end point is slightly larger than the volume actually used. Since we performed three tests and were able to publish the results of the first test when not processed, this would probably not have a significant impact on permanganate determination. However, if the error were included in the data, the permanganate concentration could be lower than its actual value, which would eventually lead to an error in titration of potassium iron oxalate trihydrate. In this case, we read the upper part of the meniscus because the color and coverage of the permanganate solution is very difficult to detect. Yes, this leads to an error in the procedure. However, since the diameter of the burette is small, any error caused by this reading modification would represent a very small portion of our error rate.
Surname 6 This would cause iron (II) electron loss when iodine generates Fe ^ (4+). It is necessary to find the iron ions mole, then the iron ions mass and finally the percentage of iron ions in the unknown sample. If the evaluation is performed too quickly, oxidation of manganese is compromised, causing rapid oxidation and producing a brownish solid.
