Analysis of Phosphate
Introduction
The aim of the experiment is to determine the concentration of phosphate ions in unknown samples. A series of dilution of known concentration is performed from the phosphate working solution. Each of the prepared working standards, the unknown samples and the blank are then made to react with a mixed reagent which have been prepared after acid wash of the glasswares
Glassware
* 2 Beakers * 11 conical flasks * 9 Volumetric flasks 50 ml * 1 Volumetric flasks 1000 ml * Pipette type 1 * Pipette 25 ml * Stir rod * 11cuvette * Spectrophotometer
Chemical needs; hazards and safety precautions:
1. Sulphuric acid
It is very hazardous in case of skin contact. It is classified as corrosive, irritant and permeator.
Safety needs:
Lab coats,safety goggles and gloves should be worn to minimize risk of contact.
In case of:
• Eye Contact:
Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15minutes. Cold water may be used. Get medical attention immediately.
• Skin Contact:
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Cover the irritated skin with an emollient. Cold water may be used. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.
• Serious Skin Contact:
Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate medical attention.
• Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately.
2.ammonium heptimolybdate
Ammonium heptimolybdate e is harmful if swallowed or inhaled. It causes irritation to the eyes, skin, and respiratory tract. It affects kidneys and blood
Safety measures:
