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. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
Detailed explanation-2: -The pH value can be less than 0 for very concentrated strong acids, or greater than 14 for very concentrated strong bases. The pH scale is traceable to a set of standard solutions whose pH is established by international agreement.
Detailed explanation-3: -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: -As the pH value increases from 7 to 14, it represents an increase in the OH-ion concentration. pH scale determines the acidity or basicity of the solution.
Detailed explanation-5: -∙ so the pH is greater than 7, the solution is called basic.
