A Student in a Laboratory Performed a Titration to Find

Short Answer

A student in a laboratory performed a titration to find out the exact molarity of her unknown KOH(aq)solution. She weighed out 2.465 g of KHC₈H₄O₄, dissolved it in 100 mL of water and titrated it with the base. The equation for the reaction is:OH^-(aq)+ HC₈H₄O₄^-(aq)→ H₂O + C₈H₄O₄^2-(aq)The titration showed that 42.5 mL of the base were required to neutralize the KHC₈H₄O₄ sample. What is the molarity of the potassium hydroxide solution?
