To make a 20 ppm chlorine solution for a 250 gallon spa using liquid household bleach, you would need to add approximately 1.8 fluid ounces of 8.25% bleach to the spa water. This calculation assumes that the bleach is added to a freshly filled spa with no existing chlorine in the water. Be sure to test and adjust the chlorine levels accordingly before using the spa.
For sanitizing work surfaces, a common concentration of bleach solution is 1000-5000 ppm (parts per million). This means mixing 1 teaspoon of bleach with 1 gallon of water (for 1000 ppm) up to 5 teaspoons of bleach with 1 gallon of water (for 5000 ppm). Always ensure proper ventilation and follow manufacturer's instructions for safe and effective use.
To prepare a 100 ppm stock solution of nickel nitrate in 250 ml, first calculate the mass of nickel nitrate needed. Nickel nitrate (Ni(NO3)2·6H2O) has a molar mass of approximately 290.79 g/mol. For a 100 ppm solution, you need 100 mg of nickel nitrate in 1 liter, so for 250 ml, you would require 25 mg of nickel nitrate. Weigh out 25 mg of nickel nitrate, dissolve it in a small volume of distilled water, and then dilute the solution to a final volume of 250 ml with distilled water in a volumetric flask.
To prepare a parts per million (ppm) solution from a solid, you would first need to accurately measure the mass of the solid compound. Then, dissolve this solid in a known volume of solvent to make a specific concentration solution. Finally, calculate the ppm concentration by dividing the mass of the solid compound by the total mass of the solution and converting it to ppm.
Sodium is separated from sodium chloride by electrolysis.

1 gram per tonne is 1 ppm. So 250 grams is 250 ppm. A tonne is a metric tonne, 2214 pounds

.025 percent Solution Method: 250 ppm = the ratio 250:1,000,000 = the fraction 250/1,000,000 = the decimal value 0.00025 = the percentage .025 (i.e. 0.00025 * 100)

25 PPM then flushed out properly
To prepare a 0.2 ppm solution from a 1000 ppm solution, you would need to dilute the 1000 ppm solution by adding 5000 parts of solvent for every 1 part of the 1000 ppm solution. This means mixing 1 part of the 1000 ppm solution with 5000 parts of solvent to achieve a 0.2 ppm concentration.

Assuming that you are referring to PPM as (parts per million), you can prepare a report on the solution, depending on the different ingredients that are involved and quantity of each substance present.
To make 2 gallons of water with 100 ppm of chlorine bleach, you would need to add 2.11 milliliters of bleach.
To prepare a 2 ppm solution of nickel nitrate, you would dissolve 2 grams of nickel nitrate in enough water to make 1 liter of solution. This will result in a solution where there are 2 parts of nickel nitrate for every 1 million parts of water.
To prepare a parts per million (ppm) solution from a solid, you would first need to accurately measure the mass of the solid compound. Then, dissolve this solid in a known volume of solvent to make a specific concentration solution.
