Problem
A chemist adds 25.0mL of 0.150M sulfuric acid to an excess of solid sodium hydroxide pellets in a coffee-cup calorimeter. Assume that all of the sodium hydroxide quickly dissolves and reacts completely with the acid.
(a) Starting from the balanced molecular equation for the neutralization reaction between aqueous sulfuric acid and aqueous sodium hydroxide, write the corresponding complete ionic equation.
(b) Write the net ionic equation for the reaction.
(c) The chemist observes that no solid remains and the final solution volume is 50.0mL. Describe in detail a particulate-level sketch you would draw to represent the solution after the reaction is complete. Include relative numbers of each species present and identify any species that exist as molecules rather than ions.
(d) Calculate the number of moles of liquid water produced in this reaction.
