Diluting Solution: How to Achieve 1:10 Ratio with 7ml Ethanol and 3.2gm Leaf

AI Thread Summary
To achieve a 1:10 dilution of a solution made with 7ml of ethanol and 3.2g of leaf material, the correct approach is to add 9 times the volume of the solvent. This means that instead of adding 10 volumes of solvent, which would result in an 11-fold dilution, one should add 9 volumes of solvent to the existing solution to achieve the desired 1:10 dilution ratio.

Hi all,

I have a problem than I need to figure out.

I have added 7ml ethanol to 3.2 gm leaf(any leaf)

I have been told to dilute the solution to 1:10 ratio. How to do it?

Could you all please help me?

Now you have a solution right? To dilute the solution 10 times, add 10 times the solvent to it...

Close, but wrong. Adding 10 volumes of solvent would dilute the solution 11 times.

So I believe we have to add 9 times the solvent, sorry for that mistake...
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
