How much quantity require if Gum arabic disperse (dissolve) in 50 ml DI Water so it can be completely soluble.
Gum arabic may not readily entirely dissolve in cold water, what may be related with the actual acacia species from which the raw gum was collected, and with the processing steps that may have been taken to purify the gum or otherwise increase its commercial value. When in powder form, it may be easily dissolved in warm to boiling water. When presented as lumps or flakes, it may be found preferable to initially swell and hydrate the gum with a small quantity of cold water, to which is then added hot (to boiling) water while stirring ― but avoiding swirling, at it may induce foaming. After cooling to room temperature, a viscous and homogeneous aqueous solution should be obtained.
HI Rahul,
One gram dissolves in 2 ml of water forming a solution which flows readily and is acid to litmus.
So that makes 25g in 50ml water for your requirement.
Happy new year!
Hi
Thanks for your answer. However, I had added 0.5 g in 50 ml DI Water with Graphene oxide which could not be turned into result.

I agree with Carlos that solubility of gum arabic is dependent on several factors. I found that gum arabic is readily soluble in water and does not form too viscous solution like guar gum or chia seed gum. However, if you allow hydration of polysaccharides overnight, the solubility is enhanced.
Thank you for your answer.
Does it any affect of DI water (Water conductivity) in dispersion/dissolve of Gum arabic and Graphene oxide composition.
The information concerning the solubility of Gum Arabic you can find ib a book:
The Complete Technology Book On Natural Products (Forest Based)
by Himadri Panda. Some data on solubility - see in a file enclosed.

Thank you Leonid however water conductivity is the matter to dissolve Gum arabic
we used 5g Gum in 100ml DI water. but the solution is very very viscous and It was not flow readily. We examined with warm water but it became past form!!
