Why you use pH 10 buffer in EDTA titration and the indicator paper not be put into the solution?
A pH 10 buffer is used in EDTA titrations to ensure that the reaction occurs at a consistent pH that is optimal for the formation of metal-EDTA complexes. The indicator paper is not added to the solution because the color change of the metal-EDTA complex is independent of pH and will occur naturally when all the metal ions are chelated by the EDTA.

What is the process for determining the pH of a solution using pH indicator paper, and what role does a pH indicator paper play in this process?
To determine the pH of a solution using pH indicator paper, you first dip the paper into the solution. The paper will change color based on the acidity or alkalinity of the solution. The pH indicator paper plays a crucial role in this process by providing a visual indication of the pH level through the color change, allowing you to determine the acidity or alkalinity of the solution.
What is the process for determining the pH of a solution using pH indicator paper?
To determine the pH of a solution using pH indicator paper, you would first dip the paper into the solution. The paper will change color based on the acidity or alkalinity of the solution. You can then compare the color of the paper to a pH color chart to determine the approximate pH level of the solution.
What makes universal indicator paper turn red?
Universal indicator paper turns red when the solution has a low pH, indicating that it is acidic. The red color is a result of the indicator's chemical reaction with hydrogen ions in the solution.
How is acidic concentration of a solution determined?
The acidic concentration of a solution is typically determined using a pH meter or pH indicator paper. The pH value indicates the concentration of hydrogen ions in the solution, with lower pH values indicating higher acidity. Titration with a standardized base solution can also be used to determine the acidic concentration of a solution.
What colour will universal indicator paper go if dipped into ammonia solution?
Universal indicator paper will turn blue or blue-green when dipped into ammonia solution, indicating that the solution is basic or alkaline.
Why did the paper sink in the buffer solution?
The paper sank in the buffer solution because paper is denser than the liquid in the buffer solution. The density of the paper caused it to displace an equal volume of liquid, resulting in the paper sinking rather than floating.
What indicator in titration of sodium carbonate solution against hydrochloric acid would give a complete neutralization?
The indicator methyl orange can be used in the titration of sodium carbonate solution against hydrochloric acid to give a complete neutralization. At the endpoint, when all the carbonate ions have reacted to form bicarbonate ions, the solution will turn from yellow to pink.
How do you do a test to see if ink is an indicator?
To test if ink is an indicator, you can dip litmus paper or pH paper into the ink solution to see if there is a color change indicating a change in pH. You can also add a few drops of ink to a solution with known acidity or alkalinity to observe any visible changes in color. Additionally, you can perform a titration using the ink solution to determine its pH level.

What is an indicator and what are the common indicators used for pH?
An indicator is a substance that changes color in response to changes in pH levels. Common indicators used for pH testing include litmus paper (which turns red in acidic conditions and blue in basic conditions), phenolphthalein (which is colorless in acidic conditions and pink in basic conditions), and universal indicator solution (which changes color based on the pH of the solution).

One indicator that changes colour in an acid and alkali solution?
Litmus paper is an indicator that changes color in acid and alkali solutions. In an acid solution, litmus paper turns red, while in an alkali solution, it turns blue.
What is the main ingredients that makes litmus paper an indicator?
Cabbage solution
How do you find the pH of a solid?
You can make a PH indicator solution out of blueberry juice, or you can buy litmus paper or use an indicator solution that you can buy at the store.
