How much water must be added to 1 liter of 5 saline solution to get a 2 saline solution?

Use the equation (0.05)(1) = (0.02) x: the left side represents 5\% of 1 liter; the right side represents 2\% of some amount of water. From the equation, x = 2.5. Subtracting the 1 liter of water already present in the 5\% solution, you will find that 1.5 liters need to be added.

How many liters of a 25\% percent saline solution must be added to 3 liters of a 10\% percent saline solution to obtain a 15\% percent saline solution?

Therefore add 1.5 litres of 25\% saline to 3 litres of 10\% saline to obtain 4.5 litres of 15\% saline. In other words, it’s 1 part 25\% saline to 2 parts 10\% saline.

  7. Add 2 cups of water to a microwave-safe container.
  8. Mix in 1 teaspoon of salt.

How do you prepare a 5 WV solution?

Add enough water to bring the final volume up to 200 ml. Don’t simply measure 200 ml of water and add 10 g of salt. Adding salt changes the final volume of the solution and affects the final percentage.

How do you make a 5 percent brine solution?

Steps

  1. Step 1: Preparing the Brine. • 30 g salt per L water (or 1 oz salt per qt) for a 3\% solution. • 50 g salt per L water (or 1 1/4 oz salt per qt) for a 5\% solution.
  2. Step 1: Preparing the Brine. Heat water in a non–reactive pan, add salt, and stir until dissolved. Cool thoroughly before using.

Calculating Percent Volume/Volume (\% v/v)

  1. A percent v/v solution is calculated by the following formula using the milliliter as the base measure of volume (v):
  2. \% v/v = mL of solute/100 mL of solution.
  3. Example:
  4. X \% = 5.0 mL HCl/100 mL of solution.
  5. X/100 = 5.0/100.
  6. 100X = 500.
  7. X = 5.0\% \% v/v.
