An acid with a pH approaching 7 is a weak acid. A substance with a pH of 7 is neutral, as we have learned. As the pH of a substance rises from 7, it turns from a weak base to a strong base. A strong acid such as HCl, when mixed with water, will separate into molecules of ...
Classify the acid and base as either a strong acid (SA), weak acid (WA), a strong base (SB), or weak base (WB): KOH. Classify the acid and base as either a strong acid (SA), weak acid (WA), a strong base (SB), or weak base (WB...
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. ...
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...
Weak Base and Strong Acid Titration Weak Acid and Weak Base Titration Lesson Summary Frequently Asked Questions What happens when weak acid reacts with strong base? When a weak acid reacts with a strong base, the weak acid donates its hydrogen ion (H+) to the hydroxide ion (OH-) of th...
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...
