Ineed i will rate !
which property describes an acid but not a base?
dissociates into ions in solution
with pure metals
tastes bitter
can change the color of plant-based dyes
i think it is the second choice but i'm

I dont know which it is but i hope this helps:
 acids:
*gives off H+ ions when dissolved in water
*sour tasting
*examples vinegar, lemon juice, HCI
* reacts with metals and carbonates
* turns litmus red and cabbage dye red
bases:
*gives off OH-ions when dissolved in water
*bitter tasting 
*examples are soap, baking soda, and NaOH
*turns litmus blue and cabbage dye green

Based on that i think its reacts with metals.
