A sample containing iron is approximately 99.0% w/w Fe. Using ammonia, iron is precipitated as Fe (OH)3 which is ignited to Fe203. (a) What is the gravimetric factor for analyte Fe (AW=55.85 g/mol) and precipitate Fe203 (FW=159.69 g/mol)? (b) What mass of sample is needed to ensure that the Fe203 precipitate would weigh at least 1.00 g?
Introductlon In Part (a) of this experiment you will prepare a primary standard. Potassium hydrogen phthalate (KHP) is a monoprotic acid with the formula KHC,H.O. In this experiment KHP is used as the primary standard. A standard solution is one whose solute concentration is accurately known. If a solute can be obtained in a very pure, stable, weighable form, a primary standard solution of it can be prepared directly. You will then use the standardized sodium hydroxide solution to determine the acetic acid content of a dilute unknown solution. Procedure (0) Preparation of a Primory Standard Potassium hydrogen phthalate (KHP) is a primary standard. Weigh accurately by difference, approximately 0.8 g of KHP in a clean, dry weighing bottle and transfer it into a 250 ml conical flask. Add 75 ml of distilled water. Swirl gently. Cover the flask and leave to dissolve, swirling periodicaly. Cautlon: KHP is not highly soluble and care must be taken to ensure it is all dissolved before you…
