WebbThe equivalence point is the point where the titration curve makes the steepest drop in pH. a. Find the H 2 SO 4 volume just before the start of the steepest pH change b. Find the H 2 SO 4 volume just after the pH change has leveled off. c. Calculate the average of these points by adding them together and dividing by two. Webb27 juni 2024 · Scientific theories are subject to criteria of theoretical equivalence. This article compares two types of theoretical equivalence – one syntactic and one semantic – in the context of logical anti-exceptionalism, and argues that the syntactic approach leads to undesirable consequences.

My point in this subsection concerns what ‘models’ should be taken to be in the context of thinking about theoretical equivalence in terms of the formal properties of models associated with theories. Recall the claim that an object (mathematical ... green educational backgroundThe equivalence point, or stoichiometric point, of a chemical reaction is the point at which chemically equivalent quantities of reactants have been mixed. For an acid-base reaction the equivalence point is where the moles of acid and the moles of base would neutralize each other according to the chemical reaction. This does not necessarily imply a 1:1 molar ratio of acid:base, merely that the ratio is the same as in the chemical reaction.
