The pH value of a base is always between 7 and 14. The pH scale ranges from 0 to 14, with 7 being neutral.
Here's a more detailed explanation:
pH Scale: The pH scale is used to measure the acidity or basicity of a substance.
Acids and Bases: Acids have a pH less than 7, while bases (alkaline substances) have a pH greater than 7.
Neutral: A pH of 7 is considered neutral, meaning the substance is neither acidic nor basic.
