What makes a good pH indicator?
A good pH indicator should have a distinct color change at a specific pH range, be soluble in the solvent being used, and be stable over a range of conditions. It should also be non-toxic and easy to use.
What colour should sodium sulphate be in universal indicator?
Sodium sulfate is typically colorless in universal indicator. Universal indicator is a pH indicator that changes color based on the pH of a solution, and sodium sulfate is a neutral compound that does not significantly affect the pH.
A scientist working in a lab wants to determine the precise pH of a solution what tool should the scientist use to measure?
The scientist should use a pH meter to measure the precise pH of the solution. This device provides an accurate numerical value for the acidity or alkalinity of the solution.
How you select that which indicator should be used in any titration?
The selection of an indicator for a titration is based on the pH range over which the titration will occur. The indicator should have a color change that aligns with the pH at the equivalence point of the titration. Choosing an indicator with a pH range that encompasses the equivalence point will ensure accurate endpoint detection.
Can an indicator provide an exact pH?
An indicator can provide exact pH if you are using the neutralization titration. Paper strip pH indicator are not an exact measurement but a high, medium, and low indication of acids and bases.
How is the use of indicator paper important to scientists?
With indicator papers the pH of a liquid is evaluated. Also many indicator papers are used for testing chemicals.
How do scientists measure food pH?
Through using the universal indicator or the PH probe.
What creteria is used for chosing an indicator in acid base titration?
pH range of indicator should be in the rapid pH gradient.

If the equivalence point of a titration is 5 what range of pH should the indicator be?
An indicator should have a pKa close to the expected pH at the equivalence point. For a titration with an equivalence point at pH 5, an indicator with a pKa in the range of 4 to 6 would be suitable for visual detection of the endpoint.
What colorimetric pH indicator should you use for ammonia and hydrochloric acid titration?
Since the titration is between a strong acid and a weak base, methylorange should be suitable as the equivalence point is around pH 5. The K of the indicator should be equal to the pH at the end point. Methyl orange is that indicator
What would you use to show when an acid has completely reacted with an alkali?
A pH indicator: the color is changed at the end of the reaction, when the solution become alkaline.
What fruit and vegetable can you use as a pH indicator?
Red cabbage can be used as a pH indicator for a wide range of pH levels, showing different colors depending on the acidity or alkalinity of a substance. Similarly, beets can also be used as a pH indicator, turning different colors in acidic or basic solutions.
