Answer:

Slippery, high pH, and caustic

(last option listed)

Explanation:

sour taste - acid feature

pH < 7 - acid feature [low pH]

dissolves metal - strong acid feature

bitter taste - base feature

slippery feel - base feature

pH > 7 - base feature [high pH]

dissolves metal - strong base feature

[essentially, traits of base can be described as opposites of acid traits]

So, if you combine these traits, "Slippery, high pH, and caustic" best describes characteristics of a base
