What volume of water must be added to make decinormal solution?

What volume of water must be added to make decinormal solution?

Now V (2) should be 500 mL. You start with 100 mL so you need to add 400 mL of water. What volume of water must be added to 100 ml of 0.25 N HCl solution to make it a decinormal solution? Let ‘V’ ml.of water be added to 100 ml.of 0.25 N HCl, to make a 0.1N HCl. So 100 x 0.25= (100+ V) x 0.1. Upon solving we get V= 150.

How to calculate the final concentration of HCl solution?

There is another simple way similar to above calculations, by which you can calculate your required final concentration. Lets suppose, you want to prepare 1000 ml of 5 \% HCl solution from 37\% concentrated HCl. Take 135.13 ml of Concentrated 37 \% HCl solution and make total volume upto 1000 ml to obtain final solution with 5\% concentration.

How can I convert 37\% HCl to 5\% HCl?

To put long story short, add 640 ml of water to 100 ml of a solution of 37\% HCl in water and mix them well, to achieve a final solution with volume of 740 ml whereby the HCl is 5\% only. I would do similar to what Ajay explained. This is the volume you have from 35\%.

How much water should be added to dilute a solution?

First off: no amount of water should ever be added to a concentrated solution to dilute it. That’s bad practice, and should never be done unless it is unavoidable. The ratio of the final concentration to the initial concentration is 0.05/0.20, or one quarter.

How many moles of HCl are present in 1000ml of solution?

6.00M HCl means 6 moles of HCl are present in 1000 ml of its solution. Thus , in 1ml of its solution 0.006 moles of HCl are present. This implies , in 10ml 0.06 moles of HCl are present. We want 0.5 M HCl which means we want 0.5 moles of it in 1000ml of its solution. We have 0.06 moles of HCl .

What is the volume of solution in dilution equation?

Thus , volume of solution should be 0.12L = 120 ml. We can set these equal in a dilution equation because Molarity is Miles per Volume, and by multiplying it by Volume we get Moles on each side. Moles of solute remain equal throughout a dilution since you are just adding water.

How do you prepare a solution of hydrochloric acid and water?

So, you would prepare this solution by adding enough water to your 160-mL sample of 0.25-M hydrochloric acid solution to make the total volume of the resulting solution equal to 1.00 L.
