how wold you prepare 2.00L of 1.00M HCl solution using 6.00 M HCl?
i already found the volume of 6.00M HCl needed to be .333L. i am confused about how to actually prepare the solution. do i used a volumetric flask or any other glassware?
Yes, you take 333.33 mL of the 6M stuff, add it to a 2L volumetric flask, and make to the mark with distilled or deionized water. Note that this is different from adding 333.33 mL of the 6M stuff and ADDING (2000-333.33 = 1666.67)mL of water. If you want this to be quite accurate, I don't know how you go about measuring, exactly, an aliquot of 333.33 mL.
To prepare a 2.00L of 1.00M HCl solution using 6.00M HCl, you'll need to follow these steps:
1. Calculate the volume of 6.00M HCl required to make 2.00L of 1.00M HCl solution.
- Since the desired final concentration is 1.00M, you can use the formula: C1V1 = C2V2, where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.
- Plug in the values: C1 = 6.00M, V1 = ?, C2 = 1.00M, V2 = 2.00L.
- Rearrange the formula to solve for V1: V1 = (C2 * V2) / C1.
- Substitute the values to get: V1 = (1.00M * 2.00L) / 6.00M = 0.333L or 333mL.
- Thus, you have already calculated that you need 0.333L of 6.00M HCl.
2. Use a volumetric flask or any other appropriate glassware to prepare the solution.
- A volumetric flask is specifically designed to make solutions with accurate volumes.
- Due to the nature of HCl and its potential hazards, it is recommended to use a glassware that can withstand its corrosive properties, such as a glass volumetric flask or a glass beaker.
- Make sure to wear appropriate protective equipment, such as gloves and goggles, when handling the acid.
3. Here's how you can prepare the solution using a volumetric flask:
- Obtain a clean, dry 2.00L volumetric flask. It is essential to use the exact volume required to prepare the desired concentration.
- Add approximately half of the required volume (approximately 167mL) of distilled water to the volumetric flask using a graduated cylinder or pipette.
- Carefully add the calculated volume (0.333L or 333mL) of 6.00M HCl solution to the flask using a pipette or burette.
- Swirl the flask gently to mix the solutions.
- Once the HCl is mixed with water, add more distilled water slowly to the flask until the total volume reaches the calibration mark on the neck of the flask (2.00L).
- Continue gently swirling until the solution is thoroughly mixed.
Note: Safety precautions should be taken while handling concentrated HCl as it is a corrosive and potentially harmful compound. Make sure to work in a well-ventilated area, wear appropriate protective gear, and carefully follow your institution's guidelines for handling and disposal of hazardous substances.
