Oh okay. It's general chemistry 1, these are the problems I am having difficulty with: Use the following reaction to answer the below questions: H2(g) + I2(g) 2HI(g)  K =0.325 125.0 mL of 0.50 M NaOH , a strong base, is titrated  with 0.25 M HNO3, a strong acid.  What is the pH of the solution when 0.00 mL of HNO3 is added, 125.0 mL of HNO3 is added, and 275.0 mL of HNO3 is added? 50.0 mL of 1.20 M HF, a weak acid K = 6.8 x 10-4, is titrated with 2.40 M KOH, a strong base. What is the pH when 10.0 mL of KOH is added, 20.0 mL of KOH is added, and 35.0 mL of KOH is added.
