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...
Weak Base and Strong Acid Titration Curve 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...
更新1: In this formular: eg of weak base: NH3 + H2O --- NH3+ + OH- Where did the another H+ went to?strong acid donates H+ and weak acid doesn't refuse to donate H+ weak acid also donates H+. no matter strong acid or weak acid when a substance in solu...
Is {eq}HI {/eq} a strong acid, strong base, weak acid, or weak base? Acids and Bases: While the definition of acids and bases has been expanded by Lewis, there are no strong acids or bases that cannot be classified by the simplest definition of the Arrhenius classification of a...
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...

aWeak acid or neutral or weak basic precursor solutions are preferable to obtain single phase of LiFePO4[11 ]; strong basic condition should be avoided to prepare LiFePO4 without impurity 微弱的酸或中立或微弱的基本的前体解答是更好获得单阶段LiFePO4 (11); 应该避免强的基本的情况准备LiFePO4,不用杂质...
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 ...
