    That is not the proper procedure for making solutions for your standard curve. You do dilutions from the one before not measure ou different volumes from the 0.4 M solution.

      The period is dependent on the square root of the length. If you y=x^(1/2) on a graphing calculator, you will see a very similar shape.

    if we made fermented drink and we want to destil that mean at 65°c will come out methanol first right? and at 78°c will come out etahol ? am i right? because i got some question if i do destile i need to do at 65°c for a while or just do at 78°c instead? thanks you

    • @TimeSurfer206
      @TimeSurfer206 Год назад

      Yes, but still don't drink the product from the first 5 minutes or thereabouts after the temperature has switched. And also keep an sharp eye out for the NEXT temperature increase, which is when the water's about ready to boil off. There are toxins at that end, as well. My friend who distills says he uses a number of containers to catch the product (distillate) during his distillations, one at the beginning to catch the methanol, which he switches out to a new one after 5-10 minutes of catching it once it rose to the Ethanol Temperature. He then proceeds to switch out every half hour or so, keeping an eye on the speed of the drips. When the drips start slowing, he marks that container as the last. Once the temp spikes to 212F/100C, you're getting water. After he is done, he uses a sensor to detect the levels of methane in each container, and, if too high, he drops all that product back into the still for another run. He is dreaming of the day he can get a proper Fractional Distillation Column like those shown in these videos so he can get 95% pure Ethanol Motor Fuel in one run. So do I. I'm doing destructive distillation of wood, FOR the Methanol. I want pure methanol. Be very cautious if you are distilling Ethanol for drinking. Being poisoned by Bad Hooch is a large part of why America has an ATF. Death by Waragi is real, and not fun. Everyone I know who brews is more anal retentive about sterility than Doctors are.

      That’s outside my area of understanding, but if it makes a colored solution it seems to me that Beers Law would apply just as well as it does here. You’d have to have a way to get known concentrations for a calibration plot or be able to look up a molar extinction coefficient I’d think

    You cannot separate water and ethanol completely. They form an azeotrope due to the hydrogen bonding between water and ethanol. This causes the coalescence of the boiling points to single temperature.

    • @Mrscrapiron5
      @Mrscrapiron5 4 года назад

      Yep. But this video is made for 10th graders, so I over simplified my narrative. There still is significant separation, as the ignition test at the end shows.
