In solution dilution lingo, the notation "1:10" refers to the ratio of the amount of solute to the amount of solvent or solution. It indicates the dilution factor or the relationship between the concentrations of the original solution and the diluted solution.
Specifically, "1:10" means that for every part of the solute, you add 10 parts of the solvent or solution. This ratio is commonly expressed in terms of volume, but it can also refer to mass or moles, depending on the context.
For example, if you have 1 mL of a solute and dilute it with 10 mL of solvent or solution, the resulting solution will have a total volume of 11 mL. In this case, the dilution factor is 1:10.
The "1:10" ratio can also be expressed as a decimal or percentage. In this case, the dilution factor of 1:10 is equivalent to a dilution of 0.1 (10%) or a concentration reduction to one-tenth of the original solution.
Overall, the notation "1:10" is used to indicate the proportion between the solute and solvent or solution in the process of dilution.
