If H2O has a pKa value of 15.7 and HF has a pKa value of 3.2, which is a stronger base: OH- or F-? Explain. The K_a values for two weak acids are 7.2 \times 10^(-5) and 4.2 \times 10^(-10), respectively. What are their pK_a values?

2. pKa, also known as the acid dissociation constant or Ka value, is a specific equilibrium constant that represents an acid's ability to donate hydrogen ions.3. This equilibrium situation involves the transfer of a hydrogen ion (a proton) from an acid (HA) to water (H2O).4....
This solution was augmented with 25% (v/v) 2H2O for field locking, and then 700 μl were transferred to a 5-mm NMR tube with a septum-lined screw cap (Wilmad catalog no. 535-TR-7). A 1-mm capillary tube was filled with 0.1 mm potassium fluoride in 100 mm potassium chloride, pH...
