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.
Glucose is the solute; water is the solvent.
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).
You can use a glucose oxidase test strip or a glucose meter to detect and measure glucose levels in the sample. Alternatively, you can perform a chemical test like the Benedict's test or Fehling's solution test to confirm the presence of glucose based on color changes.
An isotonic glucose solution is a solution that has the same concentration of glucose as body fluids, such as blood. This means that the solution will not cause water to move in or out of cells, helping to maintain the balance of fluids within the body. Isotonic glucose solutions are often used in medical settings to provide hydration and energy to patients.
Hemolysis
None
The isotonic coefficient for NaCl can be calculated by dividing the concentration of the glucose solution (14M) by the concentration of the NaCl solution (0.7M). This gives an isotonic coefficient of 20 for NaCl, meaning that a solution of 0.7M NaCl is isotonic with a 14M glucose solution with respect to hemolysis.
When red blood cells are placed in a 10% glucose solution, they will undergo crenation, which is the shrinking and deformation of the cells due to water loss through osmosis. The hypertonic solution causes water to move out of the cells, resulting in the cells losing their normal shape and structure.
Glucose solution is a homogeneous mixture because it is composed of glucose dissolved in water, making it uniform throughout.

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.
