Preparation and analysis of an iron salt

Introduction
The purpose of this lab is to test the preparation of an iron salt to determine if it is a reliable and productive method. The point of the lab is to study the yield of the salt that could be obtained from the reaction, and the purity of the salt produced. To prepare the salt, specific instructions from a “medical journal” were used to obtain a salt precipitate.

Experimental
7.50 g Fe(NH4)2(SO)4)2 ּ 6 H2O was weighed on a top-loading balance and put in 25.0mL of warm water mixed with 1.00mL of 6.00M sulfuric acid. The mixture was cautiously heated to steaming and stirred. After the ferrous oxalate precipitate settled, the supernatant liquid was decanted. The oxalate was stirred with 25.0mL of warm water and was again decanted. 15.0mL of 1.80M potassium oxalate solution was added to the solid and the solution was heated to 40.0°C. 16.0mL of 7.50% H2O2 was added while the liquid was gently stirred, all while making sure the temperature stayed...
