Abstract:
pH detection is related to human beings' life closely. Herein, a porous metal hydrogen-bonded organic framework (MHOF) Co-CDI-CO32- was designed and synthesized, which could be utilized to detect the pH values of strong acids. The sensitivity of pH detection was in the range of pH 2.0-2.4 with an accuracy of 0.1, which mainly depended on the different degree of crystal surface damage. The MHOF Co-CDI-CO32- had potential applications with the advantages of low cost, easy storage, and great sensitivity for pH detection as a pH sensor.

Acid Strength and Molecular Structure
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with...
Titration of a Weak Base with a Strong Acid
Using the ICE table and substituting the Kb value, we calculate the initial pH of 50 mL of 0.1 M ammonia to be 11.11. Addition of 25 mL of 0.1 M hydrochloric acid to this solution of ammonia results in a buffer with an equal concentration of ammonia and ammonium ions. The pH of this buffer can be calculated by substituting these...
