1. 500.0 mL of 0.120 M NaOH is added to 525 mL of 0.250 M weak acid (Ka = 3.44 × 10-5). What is the pH of the resulting buffer?
2. Write the balanced neutralization reaction between H2SO4 and KOH in aqueous solution. Phases are optional. 0.550 L of 0.450 M H2SO4 is mixed with 0.500 L of 0.200 M KOH. What concentration of sulfuric acid remains after neutralization?
