We are doing a practical involving a dilution series. I've done them before, but this seems odd. Usually the dilutions are given as decimals or ratios etc. But this refers to the concentration of everything in 'vol' O.o
So we are given 20vol solution. We then need to make it into 16, 8, 4 and 2 vol solutions. It says to make the 20 into 16 we need to add 40ml of water to 160ml of the 20vol solution. And from there we need to work out how to make the weaker solutions. We have the worksheet already and there's a little box under the 8, 4 and 2 vol parts of the diagram saying that 100ml of water is needed. The diagram also shows pouring liquid from the 20 > 16 > 8 > 4 > 2 to make all the dilutions.
When I've googled dilution series, none of them mention 'vols' of anything.
We need at least 100ml of each of the solutions to then do the experiment to determine the effect of concentration.
It seems like something which should be really simple.
