Glucose solution is a homogeneous mixture because it is composed of glucose dissolved in water, making it uniform throughout.
A 30% glucose solution is purely glucose and water, though it is actually impossible to keep other contaminants out of it. To create a 30% solution of glucose, you take a fixed volume of water and add 30% of that value of glucose to the water. The amount of glucose is in grammes. For example, 3g of glucose would be added to 10ml of water.
No, glucose itself does not contain electrolytes. Electrolytes are typically ions such as sodium, potassium, chloride, and bicarbonate that can conduct electricity in solution. If electrolytes are needed, they would have to be added separately to a glucose solution.
Glucose is the solute; water is the solvent.
Isotonic solution is very close to sea water in composition and also concentration. Glucose isotonic solution is an electrolyte solution used for re-hydration. It contains salt, water and glucose.
To find the molality of a solution, you need the mass of the solvent (usually water) in kilograms and the number of moles of solute (glucose). Given that the solution is 7.80% glucose by weight, you can calculate the mass of glucose in the solution and then convert it to moles using the molar mass of glucose. From there, you can find the molality by dividing the moles of glucose by the mass of the solvent in kilograms.
Glucose is not an electrolyte in solution.
This process is called osmosis. Water molecules move from an area of low solute concentration (2% glucose solution) to an area of high solute concentration (5% glucose solution) to equalize the concentration on both sides of the membrane. This results in a net flow of water from the 2% glucose solution to the 5% glucose solution.
To prepare a 50mm glucose solution, you would need to dissolve 9g of glucose in enough water to make 100mL of solution. This would give you a solution with a concentration of 50mm (millimolar).
To make a 10% glucose solution, dissolve 10g of glucose in 90mL of water. Mix well until the glucose is completely dissolved. This will give you a total volume of 100mL of 10% glucose solution.
To find the mass of glucose in the solution, we first need to calculate the volume of glucose in the solution. Using the formula m = V x mv, we find that the mass of glucose (m) in 205 mL of a 5.50 mv glucose solution is approximately 11.28 grams.
Glucose concentration strips will work.
