The pH scale measures the acidity of a substance. It ranges from 1-14. 7 is neutral, anything below that is acid. The lower the number the more acidic the substance is. If it is higher than 7 it is alkali, which means it is a base. And the opposite of acid, the higher the number the more alkali it is.

What value is used to express the acidity or icity of a solution called?

The value used to express the acidity or basicity of a solution is called pH. pH stands for "potential of hydrogen" and is a measure of the concentration of hydrogen ions in a solution. A pH value below 7 indicates acidity, while a pH above 7 indicates alkalinity.


What is the pH of a solution defined as?

The pH of a solution is a measure of the acidity or basicity of the solution. It indicates the concentration of hydrogen ions in the solution. A pH value below 7 indicates acidity, while a pH value above 7 indicates alkalinity.


How do pH electrodes work to measure the acidity or alkalinity of a solution?

pH electrodes work by measuring the electrical potential difference between a reference electrode and a glass electrode in contact with the solution. The glass electrode responds to the hydrogen ion concentration in the solution, which is directly related to its acidity or alkalinity. The pH value is then calculated based on this potential difference, providing a measure of the solution's acidity or alkalinity.


What does pH measure directly in a solution?

pH measures the concentration of hydrogen ions in a solution, indicating whether it is acidic, neutral, or basic. A lower pH value indicates higher acidity, while a higher pH value indicates higher alkalinity.


How does pH relate to acidity?

pH is a measure of the acidity or basicity of a solution. A lower pH value indicates higher acidity, while a higher pH value indicates lower acidity and more alkalinity. pH is determined by the concentration of hydrogen ions in a solution, with more hydrogen ions leading to a lower pH (more acidic) and fewer hydrogen ions resulting in a higher pH (more basic).

Is it true that the pH scale indicates the acidity of a solution?

Yes, the pH scale measures the acidity or basicity of a solution. A pH below 7 indicates acidity, 7 is neutral, and above 7 is basic. The lower the pH value, the more acidic the solution, while a higher pH value indicates more basicity.

How does a pH probe work to measure acidity or alkalinity in a solution?

A pH probe works by measuring the concentration of hydrogen ions in a solution. It contains a special sensor that generates a small voltage based on the hydrogen ion concentration, which is then converted into a pH value. This value indicates the acidity or alkalinity of the solution, with lower pH values indicating acidity and higher values indicating alkalinity.


What is the relation between pH value and nature of the solution?

The nature of the solution be it acidic or basic will determine the PH value of the given solution.
