why would steam distillate be turbid?
404401
The turbidity is due to trace amounts of water dispersed throughout the distillate and is expected from steam distillation. It can be removed by standing the distillate over a suitable drying agent such as anhydrous MgSO4 or molecular sieve.

when they fill the tube they have 3 things that insert the paste. the gelly like paste just squeezes out and seems to be hard to mix together. if your tried hard enough, you could eventually mix it up and it would come out all muddy colored. but theres really nothing special to it.

hi there,\nits like, you need to know the temp and the mass flow rate of the bottom product of the distillation column. also you need to know the boiling point of the bottom product. the mass flow rate depends on your design calculation. temp of the bottom product you should already know. and boiling point of the bottom product is readily availble.\n\nnow use m.cp.dt to find heat required to raise the temp of the product to its boiling point. where cp is the specific heat capacity of the bottom product and is available in handbooks or sometimes expressed as functions of temperature itself. and dt stands for differnce of boiling point of bottom product and the current temp of the bottom product.call this value as h1 (say).\n\nnow you know the latent heat of vapourisation of the bottom product again refer to data handbooks for the values. multiply this by the mass flow rate. and this is the heat required to vapourise the bottoms. lets call this h2 (say)\n\nnow h1+h2, gives you the heat load for the reboiler. use this heat load to calculate the steam requirement etc...\nyou can mail me sanjaykumar_16@yahoo.com for any clarifications.

Depending on quality of the distilling process. The conductivity should be very near 0. Pure water does not conduct electricity, it is the impurities such as iron that conduct.

All of these may have an effect on absorbance since they all have the potential to affect the final concentration of the solutions being measured; In (a), you don'y know what might be in the wet stuff in the beaker, so your absorbance might go up.  In (b), because the pipet has not been "wetted" with your solution, you might pick up less than you thought, so your concentration might be lower and give a lower absorbance.  I'll let you figure out (c) for yourself since I can't be sure what you typed!

Was the glass heatproof or pyrex? Probably the rapid heating caused the problem, not the salt water directly.

This depends on what you wanted in the colorimeter in the first place, are you looking at temperature change rates going up, or down?  Either way, if you mix the two, it will skew the results of your experiment.  Hot water, even at 100 C still may have a lot of ability to absorb latent heat of vaporization before it becomes steam.  Your temperature curve will slow significantly or even flatline for a while if you are increasing temperature.  If you are decreasing temperature, hot water has already lost most of the latent heat of vaporization, it has already become liquid, this will impact your results.

I think its bcoz of some lyophobic particles present... im not sure..... jus guessin...

No safe way to do it.  Distillation perhaps, but that's not safe as sulphate fumes are not that good for you.  \n\nGrab the stock bottle and make up a fresh solution.

The bubbles contain water steam. Steam is a transparent gas, the white mist you can see above chimneys isn't steam but recondensed water in fine droplets, just as in fog or clouds.

The bubbles are steam, or water vapor.  They are NOT from hydrogen and oxygen.

I would try usuing some rubbing alcohol first. If that doesn't work, try diluting something fairly mild like the Orange Clean or Fantastic multi-purpose cleaning stuff. You definitely are right for wanting to be very careful!\n\nIf you use enough alcohol, it should defintely fix the problem!

That's water vapor you're seeing, not steam.

I use making tea as an example. You boil water and put it in a clean glass container. Add a tea bag. Watch the brown color diffuse from the bag (high concentration) to the rest of the container (low concentration). This happens without help (passive transport) down its concentration gradient.

It's the die in the soda mixed with what is normally brown stool.  It's weird, but you can get the same result with mixing water colors together.

bleach, otherwise just mountain dew

Hard to say without a picture or to see the process. Gas pressure? Wind? Contaminants in the metal? Wrong gas mixture?\nHere's a couple of links that may help..
