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 ...

Table of pKa Values for List of Acids with Conjugate Pairs - BYJU
WebOther useful tabulations of pKa values may be found on the website of Prof. ... HCl, HBr, HI, HNO3, H2SO4, HClO4. ... One can use pKa's to determine the ratio of conjugate acid to conjugate base at any "effective pH". At a pH above the pKa of an acid, the conjugate base will predominate ... 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
