Cells work best at very specific pH's, too low or high and they will not function properly.
All living things are water-based systems, which means that they depend heavily on aqueous equilibria, especially acid-base equilibria. Therefore, all the acid-base and pH concepts we have discussed so far are extremely important to biochemistry, which is the study of the chemistry of biological systems.
Just as in other acid-base systems, biological macromolecules act as acids and bases by donating and accepting protons. However, due to the size of these molecules, they often contain several different groups that accept or donate protons instead of just one such group. Thus, we talk about macromolecules as having acidic and basic groups rather than as being acids and bases. These acidic and basic groups act as weak acids and bases, with Ka values which determine the extent of dissociation of the group depending on the pH of the system. Therefore, changes in the pH around the macromolecule will determine which groups are protonated and which are not, which in turn determines properties of the molecule. This is especially important for enzymes, which are proteins that act as catalysts for important biological reactions. Most enzymes only work within a certain pH range.
Because they help maintain homeostasis within an organism by keeping pH at a nearly constant value. This is important because in humans, for example, a pH shift of about only about .4 units is fatal.
pH stands for "potential of Hydrogen" and is a measure of how acidic or basic a solution is on a scale of 0 to 14. A pH of 7 is considered neutral, while values below 7 are acidic and above 7 are basic. It is an important parameter in chemistry, biology, and environmental science.
We all know that biology can be tough sometimes but you have to think of it as this way, as a biology teacher I think that all learners should try my method. The following answers your question. If you make the pH 5 then it ill be too low for the alkali or acid to reveal its colour but if you put it at 9 it is too high. So to be safe the pH always needs to be 6-8.

pH is a measure of the acidity or alkalinity of a substance on a scale from 0 to 14, with 7 being neutral. A pH below 7 indicates acidity, while a pH above 7 indicates alkalinity. pH is important in various fields, such as chemistry, biology, and environmental science.

Scientists test the acidity or alkalinity of a substance using pH levels. This measurement helps determine the concentration of hydrogen ions in a solution. pH is important in various fields such as chemistry, biology, and environmental science.
On the pH scale, water is neutral. Water is found in all life. Also, it's a very stable substance that is easy to control.

pH determination is important because it provides information about the acidity or alkalinity of a solution. It is crucial in various fields such as chemistry, biology, and environmental science to understand how pH affects chemical reactions, biological processes, and environmental conditions. Monitoring pH levels can help in maintaining optimal conditions for processes and organisms.
pH levels indicate the acidity or alkalinity of a substance on a scale of 0-14. A pH of 7 is considered neutral, with levels below 7 being acidic and levels above 7 being alkaline. pH levels are important in various fields such as chemistry, biology, and environmental science.

LIFE - biology is literally the study of life
Calculating the pH of a solution is important because it allows us to quantify the acidity or basicity of the solution. pH values help us understand the concentration of hydrogen ions in the solution and determine if it is acidic, neutral, or basic. This information is crucial in various fields such as chemistry, biology, and environmental science to assess the behavior of different substances in a solution.
