Web16 Oct 2024 · The level to which water will rise in tightly cased wells in artesian aquifers is called the potentiometric surface. Deep wells drilled into rock to intersect the water table and reaching far below it are often called artesian wells in ordinary conversation, but this is not necessarily a correct use of the term. Web29 Oct 2024 · In an indicator based titration you add another chemical that changes color at the pH equal to the equivalence point, when the acid and base are in stoichiometric proportions. In a potentiometric titration you record the pH as you add titrant, and if the analyte is a weak acid or base you can determine its Ka or Kb.
