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:
[tex]moles HCl=molesKOH \\ \\ cHCl*vHCl=cKOH*vKOH \\ \\ cHCl= \frac{cKOH*vKOH}{vHCl}= \frac{0,890M*35mL}{25 mL}=1,246 M [/tex]
So, the concentration of the HCl solution is 1,246 M
Have a nice day!
