Final answer:
To obtain a 100 ppm chlorine solution, add 100 mg of chlorine per liter of water. For a pool requiring 3 ppm chlorine, calculate the needed chlorine mass by multiplying the desired ppm by the volume of water in liters. Chlorine is versatile in sanitization, water purification, and emergency use.
Step-by-step explanation:
To make a sanitizing solution of 100 ppm chlorine, you need to know the volume of water you are treating and the concentration of the chlorine bleach you are using. PPM stands for parts per million, so to get 100 ppm of chlorine in a given volume of water, you would add the equivalent of 100 milligrams of chlorine per liter of water.
Consider a pool that requires 3.0 ppm chlorine for sanitization. If the pool contains 21,200 kg of water, or 21,200 liters (since the density of water is about 1 kg/L), the mass of chlorine required can be calculated by multiplying the desired ppm (3.0 ppm) by the volume of water in liters. The calculation yields 63,600 mg, or 63.6 g of chlorine needed for a 5,000 gallon pool.
Understanding the use of chlorine in different concentrations and forms is essential for proper sanitization and disinfection. Chlorine is not only used for making sanitizing solutions but also in water purification, bleaching, and even in capsule form for military or emergency use.
