What best describes a stock solution that is used in a dilution?
A stock solution that is used in a dilution is known as a dilute solution. A dilute solution reduces the Ph of a chemical.
What volume of the stock solution (Part A) would contain the number of moles present in the diluted solution (Part B)?
This depends on the dilution ratio.
How do you make a 10 micromolar solution from a 100 micromolar stock solution?
5 millimolar (5 thousandths of a mole per liter) is equal to 5000 micromolar ( 5000 millionths of a mole per liter). To make a 50 micromolar solution from 5 millimolar stock solution, you therefore need 5000/50 = 100 fold dilution. Remove a 10 ml aliquot of stock and transfer to a 1000ml (1 liter) volumetric flask. Dilute with the solvent -usually water, and fill up to the graduation mark. You will now have 1 liter (1000 ml) of 50 micromolar solution.
Preparation of 100ml 0.5N from a stoke solution of 5.0N HCL?
Dilution from stock solution: Ndilution*Vdilution = Nstock*Vstock Vstock = (0.5N*100ml) / 5.0N = 10ml so take 10ml HCl from 5.0N stock solution + 90ml H2O
How do you prepare 100cm3 of 0.1M CoCl2 from a 0.5M solution of CoCl2?
So you need a 1 in 5 dilution (5x dilution i.e. 0.5/0.1), so 100/5 is 20ml stock diluted to 100ml
How much solution to 1 liter water 110 dilution?
You add 9.09ml of stock solution to a volumetric and make it up to 1 litre to get a 110 dilution

How can you make 1 in 2 dilution so that you can duplicate the measurement with little amount of stock solution i.e. you have only 1ml stock solution.?
1 part of stock+ 2part of dillution
How would you make a 1 in 4 dilution of a stock solution?
See the two Related Questions to the left for complete instructions on how to make any solution of any concentrations.To make a 1 in 4 dilution, it is best is to use a graduated cylinder. Measure out 3 parts water and add to that 1 part stock solution, which gives a total of 4 parts. For instance, if you measure out 30 mL of water, and then add 10 mL of stock solution to that, you will have a total of 40 mL solution, 1/4 the concentration of the original stock solution. (Or, equivalently if you need more than this, measure out 150 mL of water and add 50 mL of stock solution to give a total of 200 mL of the diluted solution). If you don't have a graduated cylinder, you'll need two containers: one small and one much larger. Fill the small one completely with water, and then pour that into a new (larger) container. Do that two more times (for a total of 3). Then fill the smaller container with stock solution, and add the water. When diluting acids and bases, it is extremely important to add the acid/base to water, and not the other way around! If you want to do a dilution with different numbers, just change the numbers accordingly. For example, if you want a 2 in 5 dilution, add 3 parts water to 2 parts stock solution. When it says "2 in 5" that means two parts stock solution to 5 total parts, so that leaves 3 parts water!

How do you make a 10 micromolar solution from a 100 micromolar stock solution?

To make a 50 micromolar solution from 5 millimolar stock solution, you therefore need 5000/50 = 100 fold dilution. Remove a 10 ml aliquot of stock and transfer to a 1000ml (1 liter) volumetric flask.

So you need a 1 in 5 dilution (5x dilution i.e. 0.5/0.1), so 100/5 is 20ml stock diluted to 100ml
What does it means by 100 times dilution of stock dilution?
You add 99 L to 1.0 L stock: concentrations are 100 times less.
What is sequential dilution?
In a sequential solution different volumes of a stock solution is added to varying volumes of solvent to create new solutions of specific concentration. Mostly use to create lower concentration of solutions.
How does one avoid stock dilution?
One can avoid stock dilution by keeping your shares accounted for. You need to know if the price of your shares are going up or down in your part of the company.
