The document explains how solutions are created by combining solutes and solvents, providing specific examples of calculating the amounts needed for various percentages of solutions. It includes instructions for preparing different concentrations, including a 5% dextrose solution and a 1:5000 potassium permanganate solution. The calculations involve determining the amount of solute and solvent required based on desired strengths.
Solution preparations
- 2. Solution is a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent). Solution = solute + solvent
- 3. 1.How many grams of Dextrose would there be in 500mL of 5% Dextrose?
- 4. 1.How many grams of Dextrose would there be in 100mL of 25% Dextrose?
- 5. 1. How will you prepare 10% of Dettol solution?
- 6. 2. How will you prepare 750 ml of 5% Savlon solution
- 7. Formula for Calculation of solutions Desired strength= strength of the solution required. Stock strength = strength of the concentrated solution what we have Volume required = Amount of solution to be prepared Desired Strength × Volume Required Amount of solute required = Stock Strength Water Required = Volume Required − Solute Required
- 8. How will you prepare 2000ml of 1: 5000 potassium permanganate solution
- 9. 1:5000 means that 1g of potassium permanganate is dissolved in 5000mL. Ans: 1g = 5000mL 1000mg = 5000mL ? mg =2000ml 1000mgx2000ml = ? mgx5000ml 1000mgx2000ml = ?mg 5000ml 400 mg to be mixed with 2000 ml of water to prepare 2000ml of 1:5000 solution.
