A group of students is comparing the graphs of strong acid-strong base and weak acid-strong base titration curves, where the base is the titrant. Which statement inaccurately describes a difference between the two curves?

The initial pH for the weak acid-strong base curve is higher than the initial pH for the strong acid-strong base curve.

At the equivalence points, the pH of the weak acid-strong base is greater than the pH of the strong acid-strong base.

At the half-equivalence points, the pH of the weak acid-strong base is greater than the pH of the strong acid-strong base.

The steep-rise interval in the weak acid-strong base curve is more pronounced than in the strong acid-strong base curve.

I know the answer is NOT A or B

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
