This reaction gives the methanol solvate of the dichloride, which upon heating in a vacuum at about 160 °C converts to anhydrous FeCl 2. [4] The net reaction is shown: Fe + 2 HCl → FeCl 2 + H 2. FeBr 2 and FeI 2 can be prepared analogously. An alternative synthesis of anhydrous ferrous chloride is the reduction of FeCl 3 with chlorobenzene: [5]
Urine electrolyte levels can be measured in a medical laboratory for diagnostic purposes. The urine concentrations of sodium , chlorine and potassium may be used to investigate conditions such as abnormal blood electrolyte levels, acute kidney injury , metabolic alkalosis and hypovolemia .
The interpretation of urinalysis takes into account the results of physical, chemical and microscopic examination and the person's overall condition. Urine test results should always be interpreted using the reference range provided by the laboratory that performed the test, or using information provided by the test strip/device manufacturer.

2 FeCl 3 + Fe → 3 FeCl 2. A traditional synthesis of anhydrous ferrous chloride is the reduction of FeCl 3 with chlorobenzene: [25] 2 FeCl 3 + C 6 H 5 Cl → 2 FeCl 2 + C 6 H 4 Cl 2 + HCl. iron(III) chloride releases chlorine gas when heated above 160 °C, generating ferrous chloride: [16] 2FeCl 3 → 2FeCl 2 + Cl 2
