∙ 7y agoThe scientist can gradually add small amounts of the acid to the solution while monitoring the pH using a pH meter. Once the pH reaches the desired point, they can stop and note the amount of acid added. This experiment can be replicated multiple times to ensure consistency and accuracy in the results.
The scientist is testing the solution's buffer capacity, which is its ability to resist changes in pH when an acid is added. By determining the point where the pH drops below 4.0, the scientist can determine the maximum amount of acid the solution can neutralize before its pH becomes too acidic, which is crucial for various experiments or applications.
The scientist can gradually add the acid to the solution, measuring the pH at each addition, until the pH drops below the desired point. By monitoring this change, the scientist can determine the maximum amount of acid that can be added before reaching the desired pH. Controlled conditions and accurate measurements are essential for reliable results.
Methyl yellow, which changes from yellow to red around a pH of 4.0
The term for a substance that changes color according to the pH of the solution is an indicator. Indicators are commonly used in chemistry to visually determine the acidity or basicity of a solution based on color changes.
In base solution, Congo red appears blue.

Experiment- "In a experiment, the scientist deliberately makes certain changes in the world about him so that he can observe the consequences."

An artificial situation created by a scientist to observe the consequences of specific changes is called an experiment. In an experiment, the scientist manipulates variables to test hypotheses and determine the impact of those changes under controlled conditions. This method allows for the identification of cause-and-effect relationships in the natural world.

No. They can, however, trace it back and extrapolate possible future changes in certain circumstances
The variable that a scientist changes in an experiment is called the independent variable. This is the variable that the scientist manipulates to observe its effect on the dependent variable.
The independent variable is the variable that a scientist changes when conducting an experiment. It is the factor that the scientist manipulates to see how it affects the outcome or dependent variable.
The variable that a scientist changes is called the independent variable. This is the factor that is manipulated by the scientist in an experiment to see the effect it has on another variable, called the dependent variable.
