Which of the following material(s) and equipment are necessary to acquire the above graph? Mark all that apply. Make sure to have your answer in alphabetical order.
A. An acid.

B. A Base.

C. An indicator.

D. A pH meter.

E. A Burette.

  A, B, D, E

Explanation:

This titration involved adding measured amounts of an acid (HCl) to a base, and recording quantitative measurements of the resulting pH. The necessary equipment includes ...

an acid (specifically, HCl)a basea pH meter for quantitative measurements of pHa device for precisely measuring the acid (a burette works for this)

We believe these requirements are consistent with choices A, B, D, E from the list given.

An "indicator" will typically change some obvious property (often, color) at a specific value of pH. It generally is not quantitative enough for the purpose of drawing the supplied graph. A pH meter is a better choice.

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.
