    Ph
In summary, there are practical examples of strong acids/bases having a negative pH, such as superacids. There is no limit to the range of possible pH values. However, for solutions that follow Ostwald's dilution principle, the pH is typically between 0 and 14, with some deviation in very dilute and concentrated solutions.

Is it really possible to have strong acid/bases with a negative pH in practice, or is it purely theoretical. Like we say 10M HCl has pH = -1, does it really?

Is there something that limits the range of possible pH values for a solution?

Yes it is possible and does happen, just browse yahoo and look up "superacids", you can easily have a negative pH of -1. And there are NO limits for a pH value.

There is a law called Ostwald's dilution principle, and it states that pH is within 0 and 14 for solutions obeying this law. The response for pH with respect to concentration is somewhat deviated in very dilute and concentrated solutions.
 

1. What is pH and why is it important?

pH is a measure of the acidity or basicity of a solution. It is important because it affects the chemical reactions and properties of substances, as well as the biological processes in living organisms.

2. How is pH measured and what is the pH scale?

pH is measured on a scale of 0-14, with 7 being neutral. The lower the pH, the more acidic the solution, and the higher the pH, the more basic the solution. pH can be measured using pH paper, a pH meter, or indicators such as litmus paper.

3. What factors can affect pH?

The concentration of hydrogen ions (H+) and hydroxide ions (OH-) can affect pH, as well as the presence of acids, bases, and buffers. Temperature, pressure, and dilution can also impact pH levels.

4. How does pH affect living organisms?

Living organisms have a specific pH range in which they can survive and function properly. Changes in pH can disrupt biological processes and cause harm to cells and tissues. For example, a decrease in blood pH can lead to acidosis, while an increase in blood pH can cause alkalosis.

5. Can pH be changed or controlled?

pH can be changed or controlled through the addition of acids, bases, or buffers to a solution. Drinking water and foods can also affect the pH of our bodies. Our bodies also have natural mechanisms, such as the respiratory and renal systems, to regulate and maintain pH levels within a narrow range.
