Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where on the pH scale would you find bases?
A
0-6
B
7
C
8-14
D
None of the above
Explanation: 

Detailed explanation-1: -pH is a measure of how acidic/basic water is. 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 numbers 8-14 on the pH scale indicate an alkaline solution. That is, it has more OH-then H+ ions. Examples of a base would be baking sugar, ammonia, sea water, and lye. The numbers 8-14 on the scale are increasing alkalinity.

Detailed explanation-3: -Detailed Description. The pH scale measures how acidic an object is. Objects that are not very acidic are called basic. The scale has values ranging from zero (the most acidic) to 14 (the most basic).

Detailed explanation-4: -A solution with a pH of 11 is more basic than a solution with a pH of 8. This is because a pH value greater than 7 indicates a basic solution. As the pH value increases from 7 to 14, there is an increase in the concentration of OH-, which increases the strength of the solution.

Detailed explanation-5: -Alkaline cleaning agents have a Ph level above 7, ranging from 8-14-they clean grease, oils, proteins, and fats. Examples of alkaline cleaners are bleach, ammonia, borax, tub and tile, and oven cleaners.
