It's a much simpler way to compare the acidic or basic value of a given solution. pH = 4 looks a lot cleaner than 1.0 x 10^-4 M, if you ask me.

The pH scale typically ranges from 0 to 14 because it covers the full range of acidity and alkalinity levels. A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline. This range allows for precise measurement and easy comparison of solutions based on their acidity or alkalinity.
No, the pH value is not unitless. It is a unit of measurement that indicates the acidity or alkalinity of a substance on a scale of 0 to 14.
The pH value of egg whites is approximately 7.6, making it slightly basic in nature.
No, a pH value of 14 is actually very basic. pH values range from 0 to 14, with values below 7 being acidic, 7 being neutral, and values above 7 being basic. A pH of 14 indicates a strong alkaline solution.
A strong acid has a pH value close to 0, a strong base has a pH value close to 14, and a neutral substance has a pH value of 7.
To find the pH of a solution, you can use a pH meter or pH strips. The pH scale ranges from 0 to 14, with 7 being neutral. A pH below 7 is acidic, while a pH above 7 is basic. Measure the pH by dipping the pH meter or strip into the solution and reading the value displayed.
