a) Write an overall balanced equation and a net ionic equation for the complete neutralization of aqueous H2SO4 with aqueous NaOH. Be sure to include phase designations such as (s) and (aq).
b) If 60.0 grams of NaOH is used to neutralize 1.0 L of 0.500 M H2SO4, what reactant is in excess? Is the resulting solution acidic or basic?
c) Assuming that the volume is still 1.0 L, find the concentrations of all ions left in solution after the
