How do you make 5 fold dilution?
1 ml solute to 19 mls solvent. This gives a total volume of 20 (20 fold)
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.
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.
How do you make a 1 to 100 dilution from a 1 to 10 dilution?
To make a 1 to 100 dilution from a 1 to 10 dilution, first take 1 part of the 1 to 10 dilution and add it to 9 parts of diluent (such as water or buffer). This results in a 1 to 100 dilution because the original 1 to 10 dilution is already diluted, and further diluting it by 10 times achieves the desired concentration. Ensure thorough mixing to achieve uniformity.
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.
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 would you prepare a series of dilutions to get a final dilution of 10-10?
To prepare a final dilution of 10^-10, you can start with a stock solution at a known concentration. First, create a 10^-1 dilution by mixing 1 part stock solution with 9 parts diluent (e.g., sterile water). Then, take 1 part of this 10^-1 dilution and mix it with 9 parts diluent to create a 10^-2 dilution. Repeat this step until you reach the desired 10^-10 dilution, performing a series of ten 1:10 dilutions.
How to make 10 percentage dilution?
take 1 ml, add 9 ml water.
How do you get 0.1M from 1M HCL?
To make a 0.1M solution from a 1M HCL solution, you would dilute the 1M HCL with 10 parts of water (or whatever solvent you are using). For example, mix 1 mL of 1M HCL with 9 mL of water to obtain a 0.1M HCL solution.
What dilution to make 50percent acetone control?
To make a 50% acetone control, you can mix equal parts of acetone and water. For example, if you start with 10 ml of acetone, you would add 10 ml of water to make a 50% acetone solution.
