the solution of known concentration added from the burette in titration

the solution of unknown concentration in the conical flask in titration

the amount of a solute dissolved in a certain volume of solvent

readings within a certain range; for titrations, these usually need to be within ±0.10 cm³ of each other

the volume of titrant needed to reach the end point in a titration

Titrations: analytical technique

Chemistry

In the Electrolysis unit, pupils will build on their understanding of chemical reactions to explore the process of electrolysis and its applications.

In the Acids and Bases unit, pupils learned about the properties of acids, bases, and alkalis, and the reactions between them to form salts and water.

This unit explores empirical formulae, balanced chemical and ionic equations, gas identification, acid reactions, and pH as a measure of hydrogen ion concentration. It covers separation techniques and focuses on planning experiments, accurate measurements, safety, and communicating findings.

Solution of known concentration in the burette.

Solution of unknown concentration in the conical flask.

Volume of titrant needed to reach the end point.

Match the following key terms to its definition.

Why is it important to perform a trial titration first?

Why is acid added drop by drop near the end point in titration?  

Perform a trial titration to estimate the amount of titrant needed.

Fill the burette with the titrant (acid).

Add the analyte (alkali) to the conical flask.

Add indicator to the analyte in the flask.

Begin adding titrant quickly from the burette.

Slow down and add drop by drop near the end point.

Stop when the indicator changes colour and stays that colour.

Sort the steps of a titration into the correct order, starting with performing a trial titration. 

At what point should you take the volume reading from a burette?

What does it mean if titres are concordant?  

To completely neutralise an acid with an alkali.

What is titration used for in chemistry?  

A technique to find volumes of reacting solutions.

The space matter occupies, often in cm³.

When enough solution is added for a complete reaction.

Match the following terms from titrations to their correct definitions.

What is the curve on the surface of a liquid in a container called?

The indicator changes colour and stays that colour.

The indicator changes colour briefly, then fades.
