Question

This is based off of a titration performed in my chemistry lab.

At the molecular level, what species are present in the flask at the equivalance point (pH=7)? As the titration progressed, which chemical species increased in number & which decreased? please explain in detail.

ftt the morecwar leve, What Species are prerent in the NadH uk at the equivaience point Base progrased, which Chemica species incrcased in number Which deareased ? 96/ Indicator Acid of unknown concentration-

Answer 1

In the presence of a titration of a strong acid with a strong base, in the neutral pH (pH = 7) all H + ion with all OH-added ion has been neutralized, this means that the species that are in solution at that point They are NaCl and H2O.

When adding more NaOH after the equivalence point (pH = 7), there is an excess of OH- ions, which increases its concentration and in turn, increasing the alkalinity of the solution, which is measured by the variable pOH, which is proportional to the concentration of free OH-ions in the solution.

If you liked the answer, please rate it in a positive way, you would help me a lot, thank you.
