1. Calculate the pH during the titration of 25.00 mL of 0.1000 M HF(aq) with 0.1000 M RbOH(aq) after 15 mL of the base have been added. Ka of HF = 7.4 x 10-4.

2. A buffer consists of 0.33 M H3PO4 and 0.1 M NaH2PO4. Given that the K values for H3PO4 are, Ka1 = 7.2 x 10-3, Ka2 = 6.3 x 10-8, and Ka3 = 4.2 x 10-13, calculate the pH for this buffer.

3. Determine the volume in mL of 0.22 M NaOH(aq) needed to reach the half equivalence (stoichiometric) point in the titration of 36 mL of 0.18 M C6H5COOH(aq). The Ka of benzoic acid is 6.5 x 10-5.
