Answer to Question 1

ANS: C
A voltage of 61.5 mV is developed for every pH unit difference between the sample and the measuring electrode, which remains 6.84. Therefore, the voltage difference is 18.7 mV divided by 61.5 mV, or 0.30. The resultant pH can be calculated as 6.84 + 0.30 = 7.14.

Answer to Question 2

ANS: C
A voltage of 61.5 mV is developed for every pH unit difference between the sample and the measuring electrode, which remains 6.84. Therefore, the voltage difference is 44.90 mV divided by 61.5 mV, or 0.73. The resultant pH can be calculated as 6.84 + 0.73 = 7.57.
