Detailed explanation-1: -As this diagram shows, pH ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).
Detailed explanation-2: -Note that pH scale and proton concentration works in reverse direction, one increases so the other decreases. The pH Scale at normal room temperature is from 0 to 14 (debatable) and 7 is neutral (no excess proton or no deficiency of proton) and 0-7 is acidic (excess proton) wheras 7-14 is basic (deficiency of proton).
Detailed explanation-3: -If the pH of a solution is less than 7, the solution is called acidic; In an acidic solution, then, the concentration of hydrogen ions is greater than the concentration of hydroxide ions. if the pH is about 7, the solution is neutral; if the pH is greater than 7, the solution is called basic.
