To prepare a hydroponic solution with 35 mg/L of phosphorus in a 500 mL volume, you will need to dilute the concentrated calcium dihydrogen phosphate solution.
Firstly, calculate the volume of the concentrated solution required to make the desired concentration. You can apply the formula here:
C1V1 = C2V2
Where C1 is the concentration of the concentrated solution (200 mg/L), V1 is the volume of concentrated solution required, C2 is the desired concentration (35 mg/L), and V2 is the final volume of the solution (500 mL).
Substituting these values, we get:
(200 mg/L) V1 = (35 mg/L) (500 mL)
V1 = (35 mg/L) (500 mL) / (200 mg/L)
V1 = 87.5 mL
So, you need 87.5 mL of the concentrated solution to make 500 mL of the final solution with a phosphorus concentration of 35 mg/L.
To prepare the final solution, measure 87.5 mL of the concentrated solution and add it to a measuring cylinder. Add distilled water to make the remaining 500 mL, and then. Mix the solution well to ensure that the calcium dihydrogen phosphate is evenly distributed.
This will give you a hydroponic solution with a phosphorus concentration of 35 mg/L, which falls within the common range of elemental phosphorus required for growing lettuce.
What is hydroponic solution?
A Hydroponic solution, also known as hydroponic nutrient solution, is a specially formulated liquid mixture of nutrients that is used to grow plants hydroponically. Hydroponics is a method of growing plants in a soil-free medium, where the roots of the plants are suspended in a nutrient-rich solution.
