Calculating the required volume:
To prepare 0.4M NaCl from 0.3M NaCl, we need to calculate the volume of the 0.3M solution required to make a 0.4M solution.
Formula:
C1V1 = C2V2
0.3M x 100ml = 0.4M x V2
V2 = (0.3M x 100ml) / 0.4M
V2 = 75ml
Adding the necessary components:
To prepare 0.4M NaCl, we need to add 75ml of the 0.3M NaCl solution. Since we already have 100ml of the 0.3M solution, we need to add the following:
- Add 20ml water: To dilute the solution and adjust the concentration to 0.4M.
- Add 0.585g NaCl: To increase the total amount of NaCl in the solution and achieve the desired concentration.
Explanation:
Adding 20ml of water will increase the total volume of the solution without changing the amount of NaCl present, thereby increasing the concentration. Adding 0.585g of NaCl will increase the total amount of NaCl in the solution, again helping achieve the desired concentration of 0.4M.
Therefore, the correct steps to prepare 0.4M NaCl starting with 100ml of 0.3M NaCl are to add 20ml water and 0.585g NaCl.
