Detailed explanation-1: -A substance having pH 1 indicates that it is a very strong acid and those having pH 14 indicates that it is a very strong base. Q. What will be the pH value of the strongest base?
Detailed explanation-2: -Strong bases on the other hand have a pH close to 14 while weak bases have a pH just above 7.
Detailed explanation-3: -A solution of a strong alkali, such as sodium hydroxide, at concentration 1 mol dm−3, has a pH of 14.
Detailed explanation-4: -Strong bases have very high pH values, usually about 12 to 14. Well-known examples of strong bases include caustic soda or sodium hydroxide (NaOH), as well as lye or potassium hydroxide (KOH).
Detailed explanation-5: -Alkaline solutions have pH values below 7. A base is a compound that produces OH– ions in solution. Strong bases have pH values ranging from 11 to 14.
