1. Consider the following graph showing the error in determining pH using different glass electrodes. -1.0 A: Corning 015, H2SO4 B: Corning 015, HCI C: Corning 015, 1 M Nat D: Beckman-GP, 1 M Nat E: L & N Black Dot, 1 M Nat -0.5 F: Beckman Type E, 1 M Na Error, ΔpH A B 0.5 -2 0 2 6 8 10 12 14 pH a) A Beckman Type E glass electrode was used to measure the pH of a solution containing 1M Nat with a true pH of 13, what pH this glass electrode shows ? (1 point) b) What is the origin of the difference in pH? (1 point) c) What pH a Corning 015 glass electrode shows in a 5 M H2SO4 solution? (1 point) d) What is the origin of the difference in pH? (1 point)
