How would you prepare working solution : 50% NaCI (total volume and final working concentration). In your description, you will need to detail what glassware you would use, how you measure the volume and what you would use to store the solution. For the pH adjustment, you will indicate what you use to adjust the pH. Preparing a 50% NaCl Solution: Guidelines for Measuring, Adjusting pH, and Storage

How to prepare a 50% NaCl solution: Guidelines for measuring, adjusting pH and storage
To prepare 50% NaCl solution, you will need to use the following glassware: a pH meter, graduated cylinder and beaker. While the graduated cylinder measures the volume of the water, the beaker mixes the NaCl in the water. The pH meter can then be used to determine the pH and adjust it to desired levels. The graduated cylinder measures the water volume and can also be used for measuring the water content of the solution. You should place the graduated cylindrical on a flat surface. The liquid should then be filled up to the marked mark. Once the volume of water has been determined, then calculate how much NaCl you need. 250g is sufficient for 500mL of 50% NaCl solution. Once the NaCl is added, it should be stirred into the water until the solution has completely disintegrated. You should measure the pH with a pH tester and adjust the pH to your desired level. You can do this by adding sodium bicarbonate or sodium phosphate to the solution. Finally, you should store the solution in a container that is suitable. You can use a clear glass or plastic container to store the solution. You should ensure the container is completely clean before you store the solution. Cont…..
