Problem
A student combines 25.0 mL of 1.00 M sulfuric acid with 75.0 mL of 0.500 M potassium hydroxide in a coffee-cup calorimeter at 25 °C. The acid–base reaction proceeds to completion.
Answer the following questions.
(a) Write the balanced molecular equation for the reaction that occurs.
(b) Calculate the number of moles of the limiting reagent consumed in the reaction.
(c) Write the balanced net ionic equation for the reaction.
(d) Identify all spectator ions present after the reaction has reached completion and determine their molar concentration in the final reaction mixture. Assume volumes are additive and temperature changes are negligible.
