The molarity of the KOH solution can be found using the neutralization reaction equation and the concept of molarity (M = moles/L). In a neutralization reaction, the moles of H+ from HCl will equal the moles of OH- from KOH. Given that HCl and KOH react in a 1:1 molar ratio, we can set up the equation: (Volume of HCl) x (Molarity of HCl) = (Volume of KOH) x (Molarity of KOH). Plugging in the given values: (35.0 mL) x (0.200 M) = (25.0 mL) x (Molarity of KOH). Solving for the molarity of KOH gives 0.280 M.
