Problem: Do all titrations of a strong base with a strong add have the same PH at the equivalence point? a) No, it depends on the concentrations of the acid and base that are mixed together. b) No, it depends on what the conjugate base and conjugate acid are after the neutralization is complete. c) Yes, all strong base-strong acid titrations end with the same PH because the conjugate acid and conjugate base are neutral. d) Yes, all strong base-strong acid titrations end with the same PH because there is only water left in the beaker once neutralization is complete.

Strong base-strong acid neutralization reaction

  • base + acid    →   ionic salt       +     H2O

                                         salt of conj. base         conj. acid

                                        

At the equivalence point of a strong base-strong acid titration:


moles acid=moles base


**both get used up


strong base + strong acid → neutral salt + H2O  pH = 7

Do all titrations of a strong base with a strong add have the same PH at the equivalence point? 

a) No, it depends on the concentrations of the acid and base that are mixed together. 

b) No, it depends on what the conjugate base and conjugate acid are after the neutralization is complete. 

c) Yes, all strong base-strong acid titrations end with the same PH because the conjugate acid and conjugate base are neutral. 

d) Yes, all strong base-strong acid titrations end with the same PH because there is only water left in the beaker once neutralization is complete.
