Describe in words how you would make a 1.00 M solution of HCl from a 5.00 M solution of HCl.
Completely stumped here. Any help?
To make a 1.00 M solution of HCl from a 5.00 M solution of HCl, you will need to dilute the concentrated solution. Dilution involves adding a solvent, typically water, to the concentrated solution to reduce its concentration.
Here's how you can do it:
1. Obtain a container or volumetric flask with a known volume. Let's assume you have a 1 liter volumetric flask.
2. Measure the desired volume of the 5.00 M HCl solution you will be using. Let's say you want to make 1 liter of the 1.00 M HCl solution.
3. Pour the measured volume of the 5.00 M HCl solution into the volumetric flask.
4. Slowly add the solvent, in this case, water, to the flask while swirling it gently. Continue adding water until the total volume reaches the mark on the flask, which is 1 liter in this case. Take care not to go over the mark.
5. Once the desired volume is reached, stop adding water and seal the flask. Make sure to mix the solution thoroughly by inverting the flask several times to ensure uniform distribution of the solute.
Now you have successfully made a 1.00 M solution of HCl from the 5.00 M solution. It is important to note that when diluting solutions, you maintain the molar amount of the solute, but the volume increases, resulting in a decrease in concentration.
