WebJan 31, 2024 · If the pH is 2 units below the pKa (i.e under more acidic conditions when you would expect the group to be protonated), the equation becomes, − 2 = logA / HA, or.01 = … WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. …

WebThe pH of of two weak acid solutions of equal concentrations are compared. HA1 has a pH of 4.5 and HA2 has a pH of 3.5 We can conclude that KA1 > KA2? True or False? As soon as possible with explanation please Question: The pH of of two weak acid solutions of equal concentrations are compared. WebApr 8, 2024 · How to Calculate pH of a Weak Acid? The pH equation can be expressed as, pH = - log [H+] However, one must determine the value of Ka (Acid dissociation constant) to evaluate [H+]. Since in weak acids, the dissociation or ionisation process is not fully complete, computing pH for the weak acid is a bit more difficult. pbs beecham house schedule

WebMay 4, 2024 · Typically you will be asked to find the pH for a weak acid solution, and you will be given the acid concentration and the K a value. Using our assumption that [H +] = [A – ]. … WebPredict which acid in each of the following pairs is the stronger and explain your reasoning for each. (a) H 2 O or HF. (b) B (OH) 3 or Al (OH) 3. (c) HSO − 3 or HSO − 4. (d) NH 3 or H 2 S. (e) H 2 O or H 2 Te. Predict which compound in each of the following pairs of compounds is more acidic and explain your reasoning for each. WebSo when we plug in that concentration, we get the pH is equal to negative log of 1.8 times 10 to the negative fifth which is equal to 4.74.
