WebThis HCl then converts 0.00315 mol HisH to a fully protonated form. The final concentration of HisH in the solution is thus 0.0111 M. The pH of the final solution can be determined by substituting the concentration values in the Henderson-Hasselbalch equation. The pKa value of 1.82 is considered in this case. The calculation is represented as ... 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 …
