Answer:

Adding a piece of Zn

Explanation:

Adding zinc (Zn) to a hydrochloric (HCl) solution will prove its acidity with a redox reaction:

Zn(s) + 2H^+(aq) \longrightarrow Zn^{+2}(aq) + H_2(g)

This reaction can be confirmed,  by the observation of little bubbles in the surface of the metal: that bubbles are the hydrogen gas generated.

anyanavicka [17]

You didn’t show the cylinder containing water, so I created one that you can use as a model (see image).

The water level was originally at 37 mL.

Then you added the ball, and it displaced its volume of water.

The new volume reading is 52 mL, so

Volume of ball = volume of displaced water = 52 mL – 37 mL = 15 mL.
