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...
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 experiment you'll understand more about chemical reactions between acids and bases and the process of titration. ...
What are 3 weak acids? Examples of weak acids include but are not limited to: HO2C2O2H - Oxalic Acid H2SO3 - Sulfouras Acid H3PO4 - Phosphoric Acid What are examples of weak bases? NH3 - Ammonia (CH3CH2)2NH - Diethylamine CH3NH2 - Methylamine Ammonia is a weak base that...
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...
Key words: Amphoteric ion exchange fiber, strong-acid/ weak-base, fabrication, structures, adsorption for amino ac- ids INTRODUCTION Among the ion exchangers, ion exchange fibers are the attractive materials for adsorption and separation. Compared with generally used granular ion exchange resins,...
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 ...
Is LiOH a strong acid, strong base, weak acid, or weak base? Arrhenius: The Arrhenius definition of acids and bases states that the classification of a molecule as either an acid or base can be done by identity of the cation or anion, respectively. ...
