Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
This ranges from 0 to 6 on a Ph scale
A
Element
B
Base
C
Neutral
D
Acid
Explanation: 

Detailed explanation-1: -The range goes from 0-14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

Detailed explanation-2: -The lower a substance’s pH, the more acidic it is. Each whole pH value below 7 (the neutral point) is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6.

Detailed explanation-3: -So, a solution of pH =2 is more acidic by 10, 000 than a solution of pH =6.

Detailed explanation-4: -A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value.
