10 Questions
What is the purpose of the experiment described in the text?
To determine the specific gravity of simple syrup using a pycnometer
Which material is NOT required for the experiment?
Burette
What is done after the pycnometer with its contents is warmed to 25°C?
Excess liquid is carefully wiped off and then weighed
What is the purpose of using due precautions when fitting the thermometer to the pycnometer?
To avoid air bubbles in the pycnometer
What temperature is the simple syrup cooled to before being filled in the pycnometer?
1-3 degrees below 25°C
What is the main purpose of using distilled water in the experiment?
To compare with the specific gravity of simple syrup
What is the formula for calculating the specific gravity of the syrup at 25°C?
Weigh the empty pycnometer, then weigh it filled with syrup at 25°C. Subtract the two weights and divide by the weight of distilled water at 25°C.
What is the purpose of a hydrometer?
To determine quickly the approximate specific gravity or density of liquids by flotation.
Why are specific gravity hydrometers usually made in sets of six?
To cover different ranges in specific gravities, allowing a complete set to suffice for various liquids.
What does a hydrometer typically consist of?
A sealed glass tube weighted with mercury and often provided with a thermometer.
