In this chemistry experiment, you'll be learning how to find the concentration of an acid using titration with a weak base. By the end of this...
The titration curve for a weak base - strong acid titration is different than that of a weak acid - strong base titration. The curve begins at pH 11 and slopes downward gradually until the equivalence point is reached. At the equivalence point, the curve slopes downward sharply and evens out...
When titrating a weak acid with a strong base, I know that the pH at the equivalence point will be higher than pH 7, since the strong base releases all its OH- ions while the weak acid only disassociates partially. But here is my problem: wouldn't the OH- and H+ form water, and...

The resulting membrane behaved as a charge-mosaic membrane at higher pH values and as an anion-exchange membrane at lower pH values, the behavior corresponding to the degree of dissociation of the carboxyl group. This weak acid-strong base type charge-mosaic membrane exhibited quite high ion ...
The flowmeter is all made of corrosion-resistant materials acid, alkali and various solvents, suitable for Accurate meter for various chemical media with medium and low viscosity that cannot be in contact with metals such as stainless steel the amount. Used in the chemical industry or reactor flow...
for weak base only some of its molecules are ionised. eg of strong base: NaOH ---> Na+ + OH- eg of weak base: NH3 + H2O ---> NH3+ + OH- when an acid mix/reacts with a base we don't call it's damaged people called neutralisation. Neutralisation is: the...
The present invention relates to a clean production process for extracting citric acid from citric acid fermented liuqor, includes the following steps: synthesizing weak-acid strong-base amphoteric resin specially used for adsorbing and separating citric acid, adopting fixed bed with said resin and ...
