Is white wine vinegar's high concentration of ethanoic acid due to its percentage of alcohol content? Why does white wine vinegar have larger acidity than distilled vinegar?

210208 • I'm investigating the concentration of ethanoic acid in white rice, sarson distilled and white wine vinegar and I am very concerned about distillation with white wine and rice vinegar because it takes me so long to distill small amount of ethanoic acid. Lets say I obtained 10 cm3 of ethanoic acid on the actual day ... how can I titrate this? I have to do at least do three titrations to get an average titre value and this seems impossible to do on this small portion of ethanoic acid?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
