When you are doing dilutions the larger number is always the total final volume. The smaller number is the amount of the solute. The larger number minus the smaller number is the amount of the solvent. So a 1:5 or a 1 IN 5 dilution would be 1 part solute and 4 parts solvent to come to a total volume of 5.
When referencing ratios in mathematics 1:5 means 1 TO 5. The ratio is relative to the two items. For every 1 of the first you have 5 of the second.
It is critical if you are making dilutions to understand the difference as the two explanations are not interchangeable.

The geometric mean of 10 and 20 is 14.1421356237
The geometric mean of 10 and 12 is: 10.9544511501
MEAN = ( 8+10 )/2 = 18/2 =9
1/10 + 1/10 = 2/10 = 1/5.
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.
It is a mixture of 1 part of the active ingredient (by volume) to 10 parts of the solvent.
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.
Add 2 mL of culture to 20 mL of buffer. 2/20 = 1/10
To dilute a 10 ppm solution to 1 ppm, you would mix 1 part of the 10 ppm solution with 9 parts of a diluent (such as water). This would result in a 1 ppm concentration because the concentration has been decreased by a factor of 10 during the dilution process.

take 1 ml, add 9 ml water.
The normal dilution rate for household bleach (sodium hypochlorite) typically ranges from 1:10 to 1:100, depending on its intended use. For disinfection purposes, a common dilution is 1 cup of bleach to 9 cups of water (1:10), while for general cleaning, a weaker solution of 1:50 is often sufficient. Always follow the manufacturer's instructions for safe and effective use.
A 2 to 1 dilution means that for every 2 parts of a concentrated solution or substance, there is 1 part of a diluent (such as water). This results in a total of 3 parts, with the final mixture having a concentration that is one-third of the original. For example, if you have 2 mL of a solution and add 1 mL of water, you create a 2 to 1 dilution.
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.
0 percent dilution means that no additional solvent or liquid has been added to a solution. The solution remains in its original concentration without any dilution.
A 1 in 50 dilution means that one part of a substance is mixed with 49 parts of a diluent, resulting in a total of 50 parts. This is often expressed as a ratio (1:50) or as a fraction (1/50), indicating that the original substance is present at a concentration of 2% (1 part out of 50). This type of dilution is commonly used in laboratories for preparing solutions with specific concentrations.
