In a thermometric titration, the reagent solution (titrant) is added to the sample at a constant rate until attaining the endpoint. The change in temperature of the reaction solution is plotted against the volume of titrant that is added.

What is thermometric titration used for?
Thermometric titration offers a specific, quick and inexpensive method of determining the sodium content.
How do you do a thermometric titration?
Which flask is used for thermometric titration?
(b) Dewar flask.
What is thermometric?
Adjective. thermometric (not comparable) Of or pertaining to the measurement of temperature. Of, pertaining to, or employing a thermometer.
What is a thermometric liquid?
[โthษrยทmษยฆmeยทtrik โฒflรผยทษd] (thermodynamics) A fluid that has properties, such as a large and uniform thermal expansion coefficient, good thermal conductivity, and chemical stability, that make it suitable for use in a thermometer.
What are the 4 types of thermometer?
- Digital thermometers.
- Ear (or tympanic) thermometers.
- Infared thermometers.
- Strip-type thermometers.
- Mercury thermometers.
What is a thermometric property give an example?
A thermometric property is any physical property that changes measurably with temperature. Note: You must use the term ‘measurably’. Examples of thermometric properties: Length of a column of liquid, e.g. mercury and alcohol thermometers.
Which substance is used in thermometer?
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
Is water a thermometric substance?
A. higher freezing point and low boiling point than other thermometric liquids.
What are the 5 five features of a good thermometer?
- A. I and II.
- B. I, II,III and IV.
- C. I, III and IV.
- D. II, III and IV.
Why is water not used in thermometer?
Water cannot be used in thermometer because of its higher freezing point and lower boiling point than other liquids . If water is used in a thermometer , it will start phase change at 0oC and 100oC and will not measure temperature , out of this range .
What are two thermometric liquids?
Thermometer liquids are mercury and alcohol.
What are thermometric liquids two examples?
A thermometric liquid is a liquid that can change its volume (increase or decrease) in accordance with surrounding temperature. In other words, thermometric liquids are used in thermometers to measure temperature. Mercury and alcohol are common thermometric liquids.
Why mercury is used as thermometric liquid?
Mercury is used in thermometers because It has a high coefficient of expansion so that even a small rise in temperature brings about sufficient expansion which can be detected in the capillary of the calibrated part of the thermometer.
What is the SI unit of temperature?
The kelvin is the SI unit of thermodynamic temperature, and one of the seven SI base units. Unusually in the SI, we also define another unit of temperature, called the degree Celsius (ยฐC). Temperature in degrees Celsius is obtained by subtracting 273.15 from the numerical value of the temperature expressed in kelvin.
What are the 7 types of thermometer?
- Digital thermometers. Digital thermometers are regarded as the fastest and most accurate type of thermometer.
- Electronic ear thermometers.
- Forehead thermometers.
- Plastic strip thermometers.
- Pacifier thermometer.
- Glass and mercury thermometers.
What are the 5 uses of thermometer?
– To measure the outdoor temperature. – To measure body temperature during a physical exam at the doctors. – To measure body temperature when someone is ill to determine if he/she has a fever. – To measure the temperature of an oven.
What is the difference between heat and temperature?
Heat is a measure of change, never a property possessed by an object or system. Therefore, it is classified as a process variable. Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (ยฐC), Kelvin(K), Fahrenheit (ยฐF), or Rankine (R).
What are the two elements of a thermometer?
A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale …
Is alcohol used in thermometer?
The alcohol thermometer is an alternative to the mercury-in-glass thermometer and has similar functions. Unlike mercury, alcohol is less toxic and will evaporate away quickly if subjected to high temperatures. Therefore, it is used to measure low temperatures.
Who invented thermometer?
Galileo Galilei invented a rudimentary water thermometer in 1593 which, for the first time, allowed temperature variations to be measured. In 1714, Gabriel Fahrenheit invented the first mercury thermometer, the modern thermometer.
What is the properties of thermometric liquid?
A thermometric liquid should have the following properties: It should be visible. It should have uniform thermal expansion. It should have a low freezing point.
What is the difference between mercury and alcohol?
Alcohol Thermometers: Alcohol thermometers are used to measure temperatures from -115ยฐC to78. 5ยฐC. Mercury Thermometers: Mercury thermometers are used to measure temperatures from โ37 to 356 ยฐC.
Why is mass not a thermometric property?
Any physical property that changes with temperature is considered as a thermometric property. Volume, resistance, pressure etc. are examples of thermometric properties. Mass which does not depend on temperature is not a thermometric property.
