What pH value represents most basic substances?

The pH scale ranges from 0 to 14 and is used to measure how acidic or basic a substance is. A pH of 7 is considered neutral, meaning it is neither acidic nor basic. As the pH value increases above 7, the substance becomes more basic (or alkaline).

A pH value of 14 indicates a highly basic solution, with substances such as sodium hydroxide commonly being found in this range. These basic solutions have a greater concentration of hydroxide ions (OH-) compared to hydrogen ions (H+), giving them their basic properties.

Therefore, a pH value of 14 represents the most basic substances, demonstrating that these solutions can neutralize acids and are often used in various applications, from cleaning products to chemical manufacturing.
