High School Chemistry Forum / How Does Aqueous Sulfuric acid contain OH- ions ??

Depends on the unit selected, but yes, that's the most common one, at least in the metric countries.

« Last post by cannabistrated on Today at 11:40:03 AM »Thanks for the update. I see some digital density readers around the $3000 range which would be best for our situation I think. I feel like each batch of oil will vary slightly even though it is the same product. The one I have in mind is Mettler Toledo 30330857 Densito Handheld Density Meter.
Once I get the density of the object is this the weight in grams per ml? Not trying to sound ignorant on chemistry but we would really like to get an accurate measurement.
We are making 1000-5000 30ml bottles of CBD oil at a time. 94% of the oil is the carrier oil (fractionated coconut oil), 5% is CBD and 1% flavoring. Since we heat and cool it to help dilute the CBD and flavoring the volume constantly changes.
Making this in an efficient procedure is also priority so waiting for a giant bath of oil to reach a desired temperature isn't optimal and most graduated cylinders that I have seen don't go much more than 5L at a time. If I am off 1% in total volume that could be the difference of 10 bottles at 30L and 30ml a bottle. This will also offset the dosage of active ingredients by 10mg for every 1% @ 30L and 30ml a bottle.
Do you have any recommendations for 50kg scales that are accurate for these needs?
I appreciate all the help and if you'd ever like any samples of product I'd definitely be willing to send some for the help.

« Last post by rolnor on Today at 09:58:18 AM »Thank you, so it's possible to do it with a strong oxidizing agent you are saying? it wont continue to COOH?
No I don't have access, I can check it out, I'd love to get access to sites that will help me know more O-chem.
I found this link that includes all oxidations of benzylic to ketones but it's still complicated,only 1 reaction contains a compound with two aryls like fluorene and the reagent is still O2 with base :/ haha.
In my case I used acetic anhydride as solvent and then you get the acylal, a acetal with two acetoxygroups. So the aldehyde is protected from oxidation to COOH, you then get the aldehyde by hydrolysis of the acylal so its twoo step procedure.

« Last post by Borek on Today at 08:15:18 AM »A lot depends on how accurately you need to measure the volume. If ±2% is OK just using a known volume bucket will probably do.
In general going the density/mass route is definitely reasonable. Just measure the density (basically that's what you are suggesting, just don't use 30 mL as a unit, nothing wrong with that number other than it makes calculations a bit awkward, 1mL that is part of the density definition is much more convenient). That is, assuming you have reasonably accurate weighing scale capable of weighing in the 50 kg range.
Just don't try to reinvent the wheel, there are well known methods of determining the density. Yes, in most cases they call for a good balance and something that allows measuring volume with a high accuracy. Graduated cylinder may be good enough for your needs, but it is definitely not the best choice in general. I would try to buy a pycnometer.

Citizen Chemist / Need help accurately measuring high volumes of liquid
« Last post by cannabistrated on Today at 07:28:16 AM »Not really sure if this is the right category but it's all foreign to me.
I am scaling up my supplement business and am trying to figure out how to accurately measure large amounts (20 liters to 50+ liters) of Fractionated Coconut Oil.
I figured I would tare a graduated cylinder on a scale, measure out 30ml of the oil once it reached 77F and see how much it weighed. Then take the total amount of ml I need and divide it by 30 and multiply the result by however much the 30ml weighed.
Am I over thinking this? Is there a better way of going about this?
