WebThe pKa value is one method used to indicate the strength of an acid. pKa is the negative log of the acid dissociation constant or Ka value. A lower pKa value indicates a stronger … WebEx. HBr → H + + Br ... Raise 10 to the power of the difference in PKa values in the conjugate acid and reactant acid. If the reaction has a weak conjugate acid and a strong reactant acid, the equilibrium constant will be high. This means that the reaction will be driven mostly to completion. Conversely, if an acid-base reaction has a strong ...

WebSo the negative log of 5.6 times 10 to the negative 10. Is going to give us a pKa value of 9.25 when we round. So pKa is equal to 9.25. So we're gonna plug that into our Henderson-Hasselbalch equation right here. So the pH of our buffer solution is equal to 9.25 plus the log of the concentration of A minus, our base. Web2 days ago · So, is NH4Br is acid or base? NH4Br is an acid. It is the salt of Hydrogen Bromide (HBr) and Ammonia (NH3). Here, it can be noted that HBr is a strong acid while NH3 is a weak base. The salts of strong acid and weak base are acidic in nature, therefore, NH4Br is acidic. It has a pKa value of ~5 in the water and a pH value of less than 7. hdfc home loan thane
