Hcl pka value
WebJun 18, 2010 · The importance of pK a values in organic chemistry can’t be overestimated, in my opinion. Not knowing pKa values in organic chemistry is like not knowing the value of the hands in poker. In this scheme, alkyl anions are the equivalent of the royal flush – they win the proton from everything underneath them in the table. Why is pK a so important? WebSince the Ka value of HCl is 10⁷. Now a pKa value is defined as [pKa = -log Ka] So, according to this condition, the pKa of HCl is: -log of 10⁷ =-7 In this step, the logarithmic …
