Acetic acid is added during barium precipitation to help maintain a slightly acidic environment, which is necessary for the successful precipitation of barium sulfate. The acetic acid helps to prevent the formation of any other barium compounds that may interfere with the precipitation process, ensuring a more accurate determination of sulfate ions in the sample.

What is the 1M acetic acid?
Add 60g of Glacial Acetic Acid to a 1 liter volumetric flask. Make up to the mark with deionized water. The result is 1M acetic acid solution.
How do you get a 5 percent diluted acetic acid from a 99 percent acetic acid solution?
To make a 5% diluted acetic acid solution, you would mix 1 part of the 99% acetic acid solution with 19 parts of water (since 1 part acetic acid solution + 19 parts water = 20 parts total solution, and 1/20 = 5%). This will result in a 5% acetic acid solution.
Why do you add acetic acid to milk as a first step in isolating casein?
Adding acetic acid to milk helps to lower the pH, which promotes the precipitation of the casein protein. When the pH is lowered, casein molecules unfold and bond together, forming curds that can be separated from the liquid whey. This is a crucial step in the process of isolating casein from milk.
How do you get Acetic anhydride?
As an anhydride, It can be prepared by dehydrating its acid, i.e. Acetic acid, by strong dessicant such as Tetraphosphorus decaoxide(P4O10) :P4O10 + 12 CH3COOH ----> 4 H3PO4 + 6(CH3CO)2O
What happend when add acetic acid to water?
They mix, and the acetic acid partially dissociates. I'm not sure what you were looking for here.
Why add CaCO3 in isolation of casein?
Calcium carbonate is added to neutralize the excess of acetic acid which remain after the precipitation of casein.
Conversion of geraniol into geranyl acetate?

Which reagent can be used to distinguish between dilute nitric acid and dilute sulphuric acid?
Add to several drops of sulfuric acid a few grains of barium chloride; a white precipitate of barium sulfate is obtained.

They mix, and the acetic acid partially dissociates. I'm not sure what you were looking for here.
Is it safe to add water to glacial acetic acid?
It is not safe to add water to glacial acetic acid as this can result in a highly exothermic reaction, leading to a release of heat and potential splattering of the corrosive acid. This reaction could cause burns, injury, or damage. It is important to always add acid to water slowly and under proper guidance to dilute it safely.
How do you prepare a solution that is 5000 PPM acetic acid?
To prepare a 5000 PPM (parts per million) acetic acid solution, you would need to dissolve a specific amount of acetic acid (in grams) in a known volume of water (in liters). The formula to calculate the amount of acetic acid needed is: Mass of acetic acid (g) = volume of solution (L) x desired concentration (PPM) / 1000000.
How you are going to prepare a solutin containing 3 percent acetic acid and 97 percent water?
Measuring 3ml of Glacial Acetic Acid in a 100ml volumetric flask and diluting the same with water upto the 100ml mark will give exactly 3% solution of Acetic Acid containing 97% water...thats all, thank you
How do you make vinegar from glacial acetic acid?
>> you cant FALSE! If you have glacial acetic acid, which is 100% acetic acid, simply add it to 9 times the amount of water. This way, you will have 10% acetic acid, which is essentially 10% tabletop vinegar. For the opposite, however, you can do as well, but it requires MUCH more effort and specialised equipment (at least a refrigerator and a vacuum pump).
