Phenol red is used as an indicator in titrations of strong acids and strong bases because it undergoes a color change in a specific pH range suitable for these titrations. It changes from red (in acidic conditions) to yellow (in basic conditions) around pH 8.2-10, making it ideal for detecting the endpoint of the titration between a strong acid and a strong base.
What else can I help you with?
What are the examples of acid base titration?
Determination of the concentration of a base by titration with acids or determination of the concentration of an acid by titration with bases. (http://en.wikipedia.org/wiki/Acid-base_titration)
What is the most appropriate indicator for the strong acid/strong base titration?
The most appropriate indicator for a strong acid/strong base titration is phenolphthalein.
What are the products of a strong acid base titration?
The products of a strong acid-base titration are water and a salt. The salt is formed from the cation of the base and the anion of the acid used in the titration.
What factors influence the pH at the equivalence point in a strong-strong titration?
The factors that influence the pH at the equivalence point in a strong-strong titration are the strength of the acid and base being titrated, the concentration of the acid and base, and the volume of the acid and base used in the titration.
What are the type of conductometric titration?
The types of conductometric titrations include strong acid-strong base titrations, weak acid-strong base titrations, weak base-strong acid titrations, and precipitation titrations. Conductometric titrations measure the change in electrical conductivity of a solution as a titrant is added, allowing for the determination of the endpoint of the reaction.

What are the different types of titration curves and how do they vary in terms of their shapes and characteristics?
There are three main types of titration curves: strong acid-strong base, weak acid-strong base, and weak acid-weak base. Strong acid-strong base titration curves have a sharp and steep pH jump at the equivalence point. Weak acid-strong base titration curves have a gradual pH change around the equivalence point. Weak acid-weak base titration curves have a more complex shape with multiple equivalence points.
Which indicator is used for the titration of weak acid and strong base?
Phenolphthalein is commonly used as the indicator for the titration of a weak acid and a strong base. It changes color from colorless to pink at the equivalence point of the titration when the weak acid is completely neutralized by the strong base.
Can a strong base be a biurette solution in titration?
Yes, a strong base can be used as the titrant solution in a titration, typically in an acid-base titration. The strong base is gradually added from the burette to neutralize the acid in the solution being titrated. This allows for the determination of the unknown concentration or volume of the acid solution.
Condutometric titration of a strong acid with a strong base?
In a conductometric titration of a strong acid with a strong base, the equivalence point is reached when all the acid has been neutralized by the base, leading to a sharp increase in conductivity. This abrupt change in conductivity is due to the formation of water, which is a good conductor of electricity. The initial conductivity is low due to the absence of ions in the strong acid solution, and it increases as ions are formed during the titration.
What is the pH at the equivalence point of a strong acid-strong base titration?
The pH at the equivalence point of a strong acid-strong base titration is 7, which is considered neutral because the strong acid (e.g., HCl) and strong base (e.g., NaOH) react completely to form water and a salt.
How do you dissolve phenol crystals?
Phenol is a strong acid so it may be neutralized by any base as NaOH
What is phenolphthalein used in titration labs?
Phenolphtalein is an indicator used to find the endpoint of a reaction (specifically an acid-base reaction). It has a pH range of 8.3 to 10.0 which means it can be used for a strong acid to strong base titration or a weak base to strong acid titration. Phenolphthalein is clear when it is in the presence of acid and pink when it is in the presence of a base.
