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.
1 ml solute to 19 mls solvent. This gives a total volume of 20 (20 fold)
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.
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.
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.
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.
measure 1 ml of the original solution and add 6.6 ml of distilled water.
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.
take 1 ml, add 9 ml water.
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.
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.
Because you probably used a 2-fold dilution. So you need to multiply your count by 2 to get the ACTUAL amount.
To find out how many ounces of chemical it would take to make 100 gallons of finished dilution at 0.5%, we can set up a proportion. Since 11 ounces of chemical are used in 10 gallons of water, we can establish the ratio of ounces of chemical to gallons of water as 11:10. By setting up a proportion and solving for x, we find that it would take 110 ounces of chemical to make 100 gallons of finished dilution at 0.5%.
