Question

Which of the following lists describes characteristics of a base?

Bitter taste, low pH, and dissolves metals
Sour taste, high pH, and caustic
Sour taste, low pH, and slippery
Slippery, high pH, and caustic

Answer 1

Slippery, high pH, and caustic

(last option listed)

Step-by-step 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

Answer 2

Option D

Step-by-step explanation:

• Bases are caustic

sour taste refers to acid hence B is wrong

Bases have pH higher than 7 so D is the correct answer
