Question

An aqueous blue solution is prepared by mixing the liquid blue with water as per quality
requirement standards in a pharmaceutical laboratory. In a typical batch of a given day,
it is required to produce 'Q' L of solution containing 'a' v/v % of component blue.
Estimate the quantity of blue and water required for the process. Comment on your
volume estimates and a possible reasoning for the same.
Solution Requirements
Volume of solution (L) = Q = 25 +0.5 * YZ
Composition of blue in solution (v/v %) = a = (13 + Z)
Additional Data
Specific volume of blue = 785 kg/m3
Molecular weight of blue = 32 g/mol
The molar volume of solution (V, in L/mol) is given by the following expression, where X1
is the mol fraction of component blue in the solution
V = 3.9E - 3 xị -26.6E - 3 X1 +40.7E - 3​

Answer 1

Explanation:

A modified Ringer's Irigation has the following formula: Sodium chloride Potassium chloride Calcium chloride PEG 3350 Water for injection to 1000 mL Assuming that 980 mL of water is used, calculate the specific gravity of the irrigation.
