Question

Which One of the following is Not a property of a base?

A.) It turns litmus blue
B.)It's pH is greater than 7
C.)It has a bitter taste
D.)It has a high concentration of [H+]

Answer 1

let's recall the characteristics of bases.

1. they have pH greater than 7 because remember that in this scale, less than 7 is acidic

2. they taste bitter while acids taste sour

3. they turn litmus paper blue, while acids turn it red

4. they have low concentration of [H+] and high concentration of [OH-]


knowing these characteristics, we can determine that D is not bases.

Answer 2

D. A high concentration of H+ is acidic.
