Final answer:
The acceptable level of bromine for a swimming pool is between 3 and 5 ppm, with 3 ppm being the correct answer from the given options. The concept of ppm is essential in pool maintenance for proper sanitation and in other applications like evaluating water quality or health indicators.
Step-by-step explanation:
The acceptable level of bromine for a swimming pool is typically between 3 and 5 parts per million (ppm). The correct answer to the given options would be C) 3 ppm, which is within the safe range for pool sanitation without being too high, which could cause skin and eye irritation.
To maintain a pool, understanding concepts such as parts per million (ppm) is crucial. It helps measure the concentration of substances like bromine and chlorine in the water. For instance, if a 5,000-gallon pool needed to achieve a chlorine concentration of 3.0 ppm, you would calculate the required mass of chlorine to be mixed into the water.
Understanding the concentration of elements and compounds in liquids goes beyond pool maintenance. For example, total dissolved solids (TDS) refer to the total amount of dissolved material in a body of water, which affects its purity and suitability for certain uses. When dealing with human health, knowing the concentration of chemicals in the bloodstream, like a bromide count, can provide important information about a person's wellbeing.
