Chem Lab Experiment 7 with correct answers 100% 2026
Chem Lab Experiment 7 with correct answers 100% 2026 One group dilutes the acetic acid to 50 ml in their titration beaker to fully cover the pH probe and another group dilutes it to 60 ml to fully cover the pH probe. Which value(s) will be different for the two groups? (I)Initial pH (after dilution, before adding NaOH) (II)volume to reach equivalence point (III)pH at equivalence point - Correct Answer I and III only What drop rate is suggested for this experiment? - Correct Answer One drop every 2 seconds. One group dilutes the hydrochloric acid to 50 ml in their titration beaker to fully cover the pH probe and another group dilutes it to 60 ml to fully cover the pH probe. Which value(s) will be different for the two groups? (I)Initial pH (after dilution, before adding NaOH) (II)volume to reach equivalence point (III)pH at equivalence point - Correct Answer I only What are the major dissolved species in an aqueous solution of 0.10 M HCl? Hint: Consider the equilibrium expression and the size of the equilibrium constant. I) HCl II) H3O+ III) Cl- IV) OH- - Correct Answer II and III What are the major dissolved specie(s) in an aqueous solution of 0.10 M acetic acid? Hint: Consider the equilibrium expression and the size of the equilibrium constant. - Correct Answer I only How does the volume of water you added to the KHP affect the volume of NaOH you need to add to reach the equivalence point? Explain. - Correct Answer It doesn't. It's the number of moles of KHP that affects the titration What volume of NaOH did you expect to need to use when you normalize the KHP solution - Correct Answer 6 +/- 2 ml Assuming the concentrations of the HCl and HAc are both 0.1M, the volume of NaOH needed to
