Dilutions within Labs
Is it common to utilize dilutions of solutions as a way to consecutively experiment with different concentrations in decreasing order? Ex: We want to see how a compound would react with different concentrations (in decreasing increments of 0.1) of calcium chloride solution; could we simply use a stock 1M solution and dilute each time to test with the next concentration?

Hi Abhinav,
I am not sure if this is what you mean but yes, we can dilute a stock solution to different concentrations to do experiments. And I am pretty sure diluting stock solution is a very common thing to do in experiments because sometimes we need a specific amount or mole of an ion to perform experiments.

I believe it is very common to dilute solutions in order to perform an experiment multiple times and get more accurate results because in my experience doing labs in my AP Chem class, for a lab on Beer's Law and spectrophotometry, we diluted a solution to different concentrations about 5 times and ran it through a machine, using the data collected to create a graph where the different molarities were used as x-axis values. Thus, I believe it is common to utilize dilution in labs in order to create graphs where the different concentrations used are the independent variables in the experiment.

Hi,
I'm not sure if you're asking whether it is common to dilute an already-prepared dilution in labs (which I don't think it is, but I'm not entirely sure), but based on my experiences from high school chemistry classes, diluting solutions of various concentrations from one stock solution is indeed quite common. I do recall one lab from AP Chem where we prepared multiple solutions of different concentrations from the same stock solution and plotted the absorbance(?) values of the different solution molarities, after all, so I guess it might be.

Re: Dilutions within Labs
As others have said, yes, it is very common to do dilutions in order to perform experiments with the various concentrations. It is generally a simple (and possibly only) way to have various concentrations of a solution for experimental purposes.
Re: Dilutions within Labs
Yes, you can do this.
This method can also be used to dilute a very concentrated solution into a very dilute solution without using a lot of a solvent by taking small volumes of the previous concentration and then diluting it with more solvent. This effectively reduces how much solvent you have to use while still achieving the same concentration.
