The ph of 100l of concentrated kcl solution
WebbIf the stock solution is 10.0% KCl and the final volume and concentration need to be 100 mL and 0.50%, respectively, then it is an easy calculation to determine how much stock solution to use: Of course, the addition of the stock solution affects the total volume of the diluted solution, but the final concentration is likely close enough even for medical … Webb26 juli 2024 · Pour the salt into a graduated cylinder or volumetric flask containing about 180 ml of water. Swirl the flask gently until all the salt dissolves. Add enough water to bring the final volume up to 200 ml. Don't simply measure 200 ml of water and add 10 g of salt. Adding salt changes the final volume of the solution and affects the final percentage.
