WebJan 26, 2024 · Then the B-H curve follows the path of a-b-c-d-e-f-a as the magnetising current flowing through the coil alternates between a positive and negative value such as the cycle of an AC voltage. This path is called a Magnetic Hysteresis Loop. The effect of magnetic hysteresis shows that the magnetisation process of a ferromagnetic core and … WebAug 14, 2024 · The pH of the sample in the flask is initially 7.00 (as expected for pure water), but it drops very rapidly as \(\ce{HCl}\) is added. Eventually the pH becomes constant at 0.70—a point well beyond its value of 1.00 with the addition of 50.0 mL of \(\ce{HCl}\) …

WebApr 14, 2024 · The curves are usually plots of pH against the volume of titrant added or more correctly against the number of equivalents added per mole of the sample. This curve empirically defines several characteristics. The precise number of each characteristic depends on the nature of the acid being titrated: WebView the full answer. Transcribed image text: On the weak base/strong acid titration curve, label A. the point where the pH corresponds to a solution of the weak base (B) in water; B. the point where the pH corresponds to a solution of the conjugate acid (BH) in water, C. the point where pH = pK, for BH+. Answer Bank B pH 7-1 mL of titrant.
