I wrote a bunch of preliminary stuff and erased it. Then I thought of measuring the pH for the weak acids. That won't work for strong acids and bases but it will for weak acids and bases.

Chemistry
Strong acids and strong bases are 100% dissociated; weak acids and weak bases dissociate less than 100%. Acids and bases neutralize each other, producing a salt and water.

Chemistry
It all depends upon how acids and bases are defined. Some acids and/or bases don't have water at all. If you are dealing with the Arrhenius theory of acids and bases, then I suppose acids produce positive ions (but not just ANY positive ion---they must be H^+) and bases ...

Chemistry
Actually, it all depends upon the definition being used for an acid and a base. If you are using the Arrhenius theory, then acids produce H^+ (technically H3O^+) and bases produce OH^- in water solution. Acids turn blue litmus paper red; bases turn red litmus paper blue. Acids...

You need to learn to read that "complicated" and spend time with it. Practice makes perfect. Arrhenius' theory--acids give H^+ in solution; bases give OH^- in solution. Bronsted/Lowry--acids are proton donors; bases are proton acceptors. Lewis--acids accept electrons; bases ...

Is these true or false: -Every Bronsted-Lowry acid is also a Lewis acid. -Conjugate acids of weak bases produce more acidic solutions than conjugate acids of strong bases. Thank you very much!

chemistry
Strong acids and strong bases don't have a Ka or pKa because they are 100% ionized. Weak acids and weak bases have only one point on the titration curve where pH = pKa an that is where the (base) formed = (acid) remaining. When that is true, then pH = pKa + log(b/a), and when ...

Chemistry
concentration is moles of acid/base per unit volume. strength is concentration of Hydronium ions per volume for acids, and of hydroxl ions per volume for bases. Few acids or bases have the same number for strength and concentration. example: citric acid, or ammonium hydroxide.

chem
Weak acids and bases ionize partially; strong acids and bases ionize 100%. Strong and weak have nothing to do with how corrosive the acid/base is. Therefore, we can have concentrated solutions of weak acids (15M acetic acid) or dilute solutions of weak acids (0.001M acetic ...
