Detailed explanation-1: -Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. pH scale, ranging from 0 (very acidic) to 14 (very basic/alkaline) and listing the pH values of common substances.
Detailed explanation-2: -The scale has values ranging from zero (the most acidic) to 14 (the most basic).
Detailed explanation-3: -The lower a substance’s pH, the more acidic it is. Each whole pH value below 7 (the neutral point) is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6.
Detailed explanation-4: -The solution which has pH of 1 is more acidic. According to the pH scale, value less than 7 on the pH scale represents an acidic solution while value greater than 7 represents a basic solution.
Detailed explanation-5: -Therefore pH1 has a hydrogen ion concentration 100 times greater than pH3. pH 1 represents strong acid, getting progressively weaker as the pH rises. pH 7 is the neutral value of pure water at 25ºC and 1 atmosphere pressure.
