Verified step by step guidance1
Understand that the pH scale is a measure of the acidity or basicity of a solution, ranging from 0 to 14.
Recognize that a pH of 7 is considered neutral, which is the pH of pure water at 25°C.
Identify that pH values less than 7 indicate acidic solutions, while pH values greater than 7 indicate basic (alkaline) solutions.
The alkaline range of the pH scale starts just above neutral (pH 7) and extends to the maximum pH value of 14.
Therefore, the entire alkaline range of the pH scale is from pH 7 to 14, as it includes all values greater than 7 up to the highest point on the scale.
