Cl- is the conjugate base. A strong acid leads to the formation of a weak conjugate base. It is believed that the weaker the conjugate base is, the stronger is the acid. For strong acids, the value of pKa is less than -1.74. For HCl, pKa is -6.3. WebApr 2, 2024 · In order to solve a question like this you need to remember a couple of relationships pertaining to pH and concentration: pH + pOH= 14 pH= - log ([H30+] 1X10-14 = [H30+][OH-]. For this problem in particular you need to connect the fact that HCl is a strong acid and therefore dissociates completely therefore if you have a [HCl] = 0.0150 M then … east greenwich public schools employment

WebpH of HCL solution is 2.60 Question2: What is the pOH of a solution that has a hydroxide ion concentration of 4.82 x 10-5 M? Answer: Given that OH-=4.82 x 10 -5 pOH=-log ( [OH - ]) pOH=-log (4.82 x 10 -5 )=- ( - 4.32) = 4.32 pOH value is 4.32 WebpOH from Molarity. We can use molarity to determine the pOH value. pOH is equivalent to the negative log of hydroxide ion (OH –) concentration. pOH = – log [OH –] By putting the value of the concentration of OH – ion, we can determine the value of pOH. Example: Calculate the pOH value of an aqueous solution whose molarity is 6.3 × 10-5 M.
