Which instrument is used in thermometric titration?

Thermistors
The most practical sensor for measuring temperature change in titrating solutions has been found to be the thermistor. Thermistors are small solid state devices which exhibit relatively large changes in electrical resistance for small changes in temperature.

What is a thermometric titration used for?

Thermometric titration is a fast analysis technique providing results in less than 3 minutes. Thermometric titration can be used for various analyses, including titrations which cannot be performed otherwise (e.g., sodium determination)

Which flask is used for thermometric titration?

(b) Dewar flask.

What is the definition of thermometric titration in chemistry?

thermometric titration in American English noun. Chemistry. titration in which the end point is determined by measuring the temperature of a solution.

Why is a Styrofoam cup used in thermometric titration?

A calorimeter is composed of an insulated container, a thermometer, a mass of water, and the system to be studied. The use of an insulated container (Styrofoam cup in this experiment) allows us to assume that there is no heat transferred through the calorimeter walls.

Why does temperature decrease in thermometric titration?

So the highest temperature is found when enough acid has been added to neutralise all of the sodium hydroxide. After this point the temperature drops because the acid now being added is at a lower temperature than the reaction mixture.

Why does the experiment used a Styrofoam cup instead of a metal one?

The use of an insulated container (Styrofoam cup in this experiment) allows us to assume that there is no heat transferred through the calorimeter walls. In other words, we can assume that the thermodynamic universe is composed of the system and the surrounding water.

What are the main sources of error in a thermometric titration?

Several factors can cause errors in titration findings, including misreading volumes, mistaken concentration values or faulty technique. Care must be taken as the solution of the known concentration is introduced into a specific volume of the unknown through laboratory glassware such as a burette or pipette.

Why is a styrofoam cup used in thermometric titration?

Why is styrofoam used as a calorimeter?

The role of the Styrofoam in a coffee cup calorimeter is that it reduces the amount of heat exchange between the water in the coffee cup and the surrounding air. The value of a lid on the coffee cup is that it also reduces the amount of heat exchange between the water and the surrounding air.
