How do you make ethanolic KOH?
dissolve KOH powder in ethanol
What is the base hydrolysis of piperine?
By addition of 10% ethanolic KOH, water and HCl
Why do you use KOH ethanol for the isolation of piperine and What are their uses?
I assume you mean ethanol + KOH? if so, in order to prevent co-precipitation of piperine and the resin acids, dilute ethanolic KOH is added to the concentrated extract to keep acidic materials in solution as their potassium salts (acid/base rxn occurs). basically it keeps impurities in solution, while piperine precipitates out.
What is the Gibbs free energy of KOH?
Del G of KOH = -379.07 Kj/mol hope it is of some use
What is the formula for the ionic compound from potassium hydroxide?
K+ and OH- is KOH -----------

How do you isolate 4-Hydroxyisoleucine from fenugreek seeds?
Ethanolic extraction will give 4hydroxyisoleucine.......
Is perfume heterogeneous or homogenous?
A perfume is a homogeneous mixture, generally an ethanolic solution.

Why use KOH in benzilic acid rearrangement?
KOH act as a nucleufeel and react with benzil OH give electrones to benzil and berak the double bond.
How many moles are in 234.1 grams of KOH?
Molar mass of KOH = 39.1+16.0+1.0 = 56.1Amount of KOH = mass of sample / molar mass = 32/56.1 = 0.570mol
