Question

Complete the sentence. The closer to 7 a substance measures on the pH scale, the ______ the compound.

saltier
more acidic
more neutral
more basic

Answer 1

The closer to 7.00 a substance measures on the pH scale, the _more neutral_ the compound.
7.00 is the pH of water, which has exactly 1 acid unit (H+) and 1 base unit (OH-). Those neutralize each other to be neither acidic, nor basic.

Answer 2

more neutral

Step-by-step explanation:

pH is defined as the negative logarithm of the concentration of hydrogen ions.

Thus,

pH = - log [H⁺]

pH scale generally runs from 1 to 14 where pH = 7 represents neutral medium, pH < 7 represents acidic medium and pH > 7 represents basic medium.

Thus, the closer the value of pH closer to 7, the more neutral is the compound.
