Instruments utilizing electrodes measure the potential difference (charge) that builds up at an interface when two different . Announcements. Return Q2 and HW1.2. I thought Q2 was reasonable – scores were o.k., but not great. Some parts of homework (e.g. I wanted you to use Excel to solve 1.2.3 and to calculate . Sx. – the standard uncertainty in the conc. – for each sample) were not clear so will make 2 points bonus (out of 6 points). Announcements. Exam 1 coming up (Mar. 7. th. ).
