Objects to be weighed in an analytical balance are not handled with bare hands to prevent contamination and ensure accuracy. Oils, moisture, and residues from skin can alter the mass of the sample, leading to erroneous measurements. Additionally, handling with gloves or tools minimizes the risk of introducing static charge, which can affect the balance's precision. This practice maintains the integrity of the measurement process and ensures reliable results.

Why is iron weighed on an analytical balance?
Iron is weighed on an analytical balance because it provides precise measurements down to very small increments, allowing for accurate determination of the iron's mass. This is especially important when working with small amounts of iron or when needing to measure its mass with high precision for experimentation or analysis.
What are the advantages of analytical balance?
An analytical balance is typically defined as a balance with a display resolution of 0.1mg. Usually it will have a draft shield around it. Although it can be used to describe any precision balance.
What is the top of a balance scale called?
The top of a balance scale is called the balance pan or balance platform. This is where the object being weighed is placed for measurement.
What is platform beam balance?
A platform beam balance is a type of weighing scale that uses a horizontal lever with a platform on one side for placing the object being weighed and calibrated weights on the other side to determine the weight of the object. It is commonly used for measuring the mass of objects in laboratory settings or industrial environments.
Why can't hot objects not be weighed without first cooling to room temperature?
A warm or hot object will create a convection current in the air around the balance pan. This fluctuating force reduces the air pressure on the balance pan and can make it difficult to obtain a stable reading.
What is the lightest weight which can be weighed in an analytical balance?
This depends on the balance model; for a typical balance this value is 0,1 mg.
Why is the iron weighed accurately on an analytical balance while the copper sulfate is weighed on a top-pan balance?
Iron may be weighed on an analytical balance because the precise measurement is important for accuracy in experiments or calculations. Copper sulfate, on the other hand, is less sensitive to small variations in weight, making a top-pan balance sufficient for its measurement.
What is the smallest mass that can be weighed on the balance?
The smallest mass that can be accurately weighed on a balance depends on the sensitivity and precision of the balance. However, most modern analytical balances can accurately measure masses as low as 0.1 milligram (0.0001 grams).
Why is iron weighed on an analytical balance?
Iron is weighed on an analytical balance because it provides precise measurements down to very small increments, allowing for accurate determination of the iron's mass. This is especially important when working with small amounts of iron or when needing to measure its mass with high precision for experimentation or analysis.
What is the platform balance used for?
It is a scale or balance having a platform on which objects are weighed -it is also called a platform scale.
What objects can be weight an spring balance?
Objects that can be weighed on a spring balance include fruits, vegetables, books, bags, and small household items. The spring balance is typically used for measuring the weight of objects that are not too heavy or bulky.
Why are objects to be weighed placed on the center of a pan?
The objects to be weighed are placed on the center of a pan so they can be weighed accurately, without the pan tipping over.
What is top pan balance?
It is used to compare the mass of two objects
