Determining Ionic StrengthUnlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency to ionize (i.e., the ionic strength) of a weak acid or base can be quantified in several ways includingKa or Kb,pKa or pKb,and percent ionization.Part APyridine is a weak base that is used in the manufacture of pesticides and plastic resins. It is also a component of cigarette smoke. Pyridine ionizes in water as follows:C5H5N+H2O?C5H5NH++OH?The pKb of pyridine is 8.75....

The strong acid H2SeO4 will completely ionize in water, however the conjugate base can then act as a acid an ionize further. The second Ka, Ka2 for HSeO4 is 1.2 x 10-2. This second Ka is not insignificant, being stronger than many other weak acids. A. Calculate the [H3O+] for a solution of 0.150 M H2SeO4. B. Using the value calculated above, calculate the value of [H3O+] for both ionizations of the acid. Grading will be based on the...

(References) Strong acids and strong bases ionize 100% in aqueous solution - HCl is a strong acid. In solution we write it as H(aq) + Cl(aq). - HF is a weak acid. In solution we write it as HF (aq). - KOH is a strong base. In solution we write it as K (aq) + OH(aq). - NH3 is a weak base. In solution we write it as NH3(aq). Exception: Since Ca(OH)2 is only slightly soluble...

Acids are proton (H+) donors. Bases are proton (H+) acceptors. Acid-base reactions are often "reversible", meaning that they can occur in both a left-to-right and a right-to-left direction. As a result, there is one acid and one base on each side of an acid-base reaction. 1. Identify the Acids and Bases on both sides of the following reactions: a. NH4+ + OH- ⟷ NH3 + H2O b. HCl + H2O ⟷ Cl- + H3O+ c. H2PO4- + H2O ⟷ HPO42- ...
