Experiment 5 Prepare and label Oral Rehydrate Salt (ORS)
Theory
A basic oral rehydration therapy solution can be prepared when packets of oral rehydration
salts are not available. The contents of one sachet of ORS to be readily soluble in one litre of
cold water to give a clear colourless solution. Moisture of the finished product at the time of
delivery is less than 2%.
Formula
   Sodium chloride            2.6 g/L
   Potassium chloride         1.5 g/L
   Sucrose (common sugar) 27 g/L or Glucose Anhydrous                13.5g/L
   Sodium bicarbonate         2.5 g/L   or Sodium citrate             2.9g/L
Apparatus: Glass beaker, measuring cylinder, digital balance, spatula etc.
Procedure
           Weigh the required amount of sucrose, NaCl, KCl and Sodium bicarbonate
           Reduce particles of each ingredient in mortal pestle and mix thoroughly in a dry
            beaker
           Fill in air tight container or aluminum sachet when moisture content is less than
            2%
           Alternatively, mix above mixture with water to produce one liter of oral
            rehydration solution.
           Always use boiled or treated water to prepare the ORS.
           Once prepared, ORS should be consumed or discarded within 12 hours if kept at
            room temperature or 24 hours if kept refrigerated.
Use
   Dehydration from acute diarrhoea.
