a ph of 5 is ______ times more ______ than a ph of 8.

a) 1000; acidic

b) 10; basic

c) 10; acidic

d) 100; acidic

e) 100; basic

Explanation:

The pH scale is logarithmic, meaning each whole pH value represents a tenfold difference in acidity or basicity. A lower pH indicates higher acidity. The difference between pH 5 and pH 8 is \(8 - 5 = 3\) pH units. So the factor is \(10^3 = 1000\), and pH 5 is more acidic than pH 8.

Answer:

A) 1000; acidic
