A strong acid; A strong base Weak Tending toward a lower price or lower prices; as, wheat is weak; a weak market. Strong (military) Not easily subdued or taken. A strong position Weak Not stiff; pliant; frail; soft; as, the weak stalk of a plant. Strong Having wealth or resources....
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...

You can use the acid equilibrium constant Kaor elsepKato determine whether an acid is strong or weak. Strong acids have high Kaor small pKavalues, while weak acids have very small Kavalues or large pKavalues. Strong and Weak vs. Concentrated and Dilute ...
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...
Strong Vs. Corrosive You candrink diluted acetic acid(the acid found in vinegar), yet drinking the same concentration of sulfuric acid would give you a chemical burn. The reason is that sulfuric acid is highly corrosive, while acetic acid is not as active. While acids tend to be corrosive,...
Are the following compounds strong acids (SA), weak acids (WA), strong bases (SB), weak bases (WB) or neutral (N) LiOH(aq) HClO_3(aq) HSO_4^-(aq) Al(OH)_3(s) H_3PO_4(aq) HNO_3(aq) Sr(OH)_2(aq) Why is a weak acid-weak base titration different from strong ac...
Strong Acids: Basics to Superacids Unveiled By Anne Marie Helmenstine, Ph.D. Ionization of Weak Acids The reaction symbol for a strong acid ionizing in water is a simple arrow facing from left to right. On the other hand, thereaction arrowfor a weak acid ionizing in water is a double ...
Strong and Weak Acids vs. Concentrated and Dilute Acids Be careful not to confuse the terms strong and weak with concentrated anddilute. A concentrated acid contains a low amount of water. In other words, the acid is concentrated. A dilute acid is an acidic solution that contains a lot of...
