What is a two-fold dilution?
A two-fold dilution involves taking a portion of a solution and mixing it with an equal volume of diluent, resulting in a solution that is half the concentration of the original. This process is often used in laboratories to decrease the concentration of a substance and make it suitable for further testing or analysis.
If 31.2 mL of water is added to 0.8 mL of drug A what is the dilution ratio?
32
Why 5-fold rotational symmetry is not possible in cube?
A cube has 3-fold rotational symmetry, meaning it can be rotated by 120 degrees and still look the same. It does not have 5-fold rotational symmetry because the cube's faces are not oriented in a way that allows for that type of symmetry. The angles between the faces do not align with the requirements for 5-fold rotational symmetry.
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 much water to add to make a 500 dilution?
To make a 500 dilution, add 1 part of the substance you are diluting to 499 parts of water. For example, if you have 1 mL of the substance, you would add 499 mL of water to make a total volume of 500 mL for the dilution.
Is it true that a ten-fold dilution of a strong acidic solution will decrease the pH by 1?
No, it is false. A ten-fold dilution of an acid will INCREASE the pH by 1 unit. Remember pH is 0-14 where 0 is most acidic. Diluting ten-fold on a logarithmic scale will increase the pH.Conversely, a ten-fold dilution of an alkali/base will increase the pH by 1 unit.
How do you make 1000-fold dilution?
To make a 1000-fold dilution, take 1 part of your concentrated solution and mix it with 999 parts of a diluent, such as water or buffer. For example, if you start with 1 mL of the concentrated solution, you would add it to 999 mL of the diluent. Mix thoroughly to ensure homogeneity. This results in a dilution where the original solution is reduced to one-thousandth of its initial concentration.
How do you make a 7.6 fold dilution?
measure 1 ml of the original solution and add 6.6 ml of distilled water.
How do you make a 10 fold dilution?
Add one part of the substance you want to dilute to nine parts water. Nine parts water plus one part substance is 10 parts. If you add one part substance to 10 parts water, you get an 11-fold dilution.
What is the explanation for tenfold dilution technique?
In ten fold dilution we add one part of the sample into the nine part of the diluent e.g. water. It will make it ten fold dilute. If we have series of tubes to dilute then after making the ten fold dilution in first tube, take the dilute sample from the first tube in same quantity as we added sample in first tube and add it to 2nd one. then then take the same quantity from 2nd one and add to third one and so on......... from the last tube we take the adjusted quantity of dilute sample and discard it. This will make the series of ten fold dilution. If you add one part substance to 10 parts of water, you get an 11-fold dilution.
What is a two-fold dilution?
A two-fold dilution involves taking a portion of a solution and mixing it with an equal volume of diluent, resulting in a solution that is half the concentration of the original. This process is often used in laboratories to decrease the concentration of a substance and make it suitable for further testing or analysis.
How do you make a 8 fold dilution?
To make an 8-fold dilution, you would mix 1 part of the substance you want to dilute with 7 parts of the diluent (usually water or buffer solution). This results in a total of 8 parts, with 1 part being the original substance and 7 parts being the diluent. This dilution reduces the concentration of the original substance by a factor of 8.
How do you make a 1 to 5 dilution?
To make a 1 to 5 dilution you mix 1 part of your substance with 4 parts water. ie: Mix 1 tablespoon of creamer with 4 tables spoons of coffee, and the coffee is 1/5 creamer now.
What do you call it when you make 5 times as much of something?
Five-fold?!
In the calculation trypan blue exclusion assayof haemocytometer why dilution factor 2 is used not 0.5?
Because you probably used a 2-fold dilution. So you need to multiply your count by 2 to get the ACTUAL amount.
Definition of dilution and dilution factor?
In chemistry and biology, the dilution factor is the total number of unit volumes in which the material is dissolved. As I understand it, the dilution refers to the dilution ratio. If you add 1 part of something to 4 parts of something else, the dilution ratio is 1 to 4. The dilution factor counts all the parts and expresses the same thing as 1 out of 5.
If 31.2 mL of water is added to 0.8 mL of drug A what is the dilution ratio?
32
