titration Flashcards
What is titration in chemistry?
Titration is a technique used to determine the concentration of a solution by reacting it with a solution of known concentration.
What is the purpose of using an indicator in a titration?
Indicators are used to signal the end point of a titration by changing color when the reaction is complete.
What is the equivalence point in a titration?
The equivalence point is the point at which the moles of acid are equal to the moles of base in a titration.
What is a burette used for in a titration?
A burette is used to accurately measure the volume of the titrant being added to the solution being titrated.
What is the formula for calculating the concentration of a solution in a titration?
Concentration = (moles of titrant) / (volume of solution)
Why is it important to swirl the flask during a titration?
Swirling the flask ensures that the reaction is mixed thoroughly and proceeds at a consistent rate.
What is the purpose of standardizing a solution in titration?
Standardizing a solution involves determining its exact concentration by titrating it against a solution of known concentration.
What is the endpoint of a titration?
The endpoint is the point at which the indicator changes color, signaling that the reaction is complete.
How does the pH change during a titration of a strong acid with a strong base?
The pH starts at a low value, rises gradually as the base is added, and then sharply increases at the equivalence point.
What is the purpose of performing a blank titration in chemistry?
A blank titration is performed to account for any impurities or contaminants in the solvent used in the titration process.
