20.0mL of HCl was just neutralized by 25.0mL of a solution of KOH with a concentration of 0.500mol/L. Write the balanced equation of the neutralization reaction and determine the molar concentration of hydrochloric acid.
The balanced chemical equation will be :
"HCl+KOH \\rightarrow KCl + H_20"
It is a double displacement reaction.
