For short explanation questions, answer in complete sentences. For calculation questions, you must show the complete solution for full marks. Remember to report your final answers with the correct units and significant figures.
11. Calculate the pH for the following aqueous solutions:a) 0.10 M NaOHb) 7.0×10" M HCI solutionc) 1.50 M of a weak acid, HA, that has a Ka value of 3.5×10-7.d) 1.00 x 10-2 M of H2SO4 (Kaz = 1.2 x 10-2)12. Consider the titration of 100.0 ml of 0.100 M H2NNH2 (Kb = 3.0 x 10-6) with 0.200 M HNO3. Calculate thePH of resulting solution after 25.0 ml of HNO; has been added.
