Something with the pH of 8 is always going to be a base no matter what. If something has the pH of 6.9 or below it always is an acid something with a pH of 8 no matter what is always a base. Neutral is the pH of 7.
Strong bases do have a pH value of approximately 11-14. The stronger a base is the closer it will be to 14, weaker bases are closer to a pH of 7.
If a substance is 8 on the pH scale that means it's basic.
Base....a very weak base
This range of pH is basic.
No. A pH in the range of 11 to 14 would be a strong or concentrated base. An acid has a pH less than 7.
the pH scale goes from 0 to 14. 0-3 is strong acid (eg. hydrochloric acid), 4-6 is not strong acid. 7 is neutral, eg. water. 8-10 is not strong alkali (base) and 11-14 is strong alkali (eg.sodium hydroxide)
pH depends on concentration. Strong bases are for example: NaOH KOH Ca(OH)2 http://en.wikipedia.org/wiki/Base_(chemistry)
It depends on the concentration of the base added. If very dilute, the pH will be slightly greater than 7 and if quite concentrated, the pH can be as high as 14. Note: If the solution is acidic, the pH will be less than 7. (Pure water has pH = 7)
a strong alkali has a strong pH of 11-14. 14 being the strongest.
The answer is true.(:

A base is a compound that produces hydroxide (OH negative) ions in solution. Basic, or alkaline, solutions contain lower of H positive ions that pure water and have pH values above 7. Strong bases, such as the lye (commonly NaOH) used in soapmaking, tend to have pH values ranging from 11 to 14.

Bases are pH of 8 or higher. A strong base is usually considered 11 - 14
a buffer is wrong, it is basic or alkaline, depending on the choices
If one were to say "an 11-strong team" they would mean they the team they had constituted of 11 members.
