Hello!


The chemical equation for the neutralization of HCl with KOH is the following:


HCl(aq) + KOH(aq) → KCl(aq) + H₂O(l)


To calculate the concentration of the unknown solution, we can apply the following equation for the equivalence point:




So, the concentration of the HCl solution is 1,246 M


Have a nice day!
