How does a ph of 3 differ from ph of 4
WebA = digits used to pH 4.5 B = digits used to pH 4.2 or 0.3 pH units below initial value (total titrant including A) Double end-point alkalinity= (2A - B) x 0.1. EXAMPLE: A sample required 120 digits to reach pH 4.5. An additional 15 digits were required to reach pH 4.2, for a total of 135 digits. Therefore, A = 120 and B = 135. WebWhy different pH meters give different value of the same sample? We have 3 pH meter, all of them give same value in buffer solutions (4, 7 and 10). But these pH meters give different...
