Four reasons:
1) If you put chemicals on the balance pan, they will contaminate the pan.
2) A lot of balances have flat pans. If you don't put the product in something, it'll get into the mechanics of your balance and mess it up.
3) Some chemicals react violently with each other when mixed. If you measured a lot of different chemicals on your balance and some of them were to fall off the edge of the pan and mix in the mechanism, you could have an explosion.
4) It's just easier to work with powders if they're in something!
What else can I help you with?
What samples are put in a dessicator?
Samples that are sensitive to moisture or require a dry environment are typically placed in a desiccator. Common items include hygroscopic chemicals, powders, electronics, and sensitive materials used in research and laboratory experiments.
When chemicals are weighed on a balance how is the pan protected?
To keep the balance clean and to keep chemicals from mixing with other chemicals. Also some chemicals can react with the metal of the balance pan and cause it to corrode or rust. Always use weighing paper or a small dish or beaker to weigh out chemicals.
Should a sample of solid or liquid ever be placed directly on the balance scale?
No way! Everyone knows that solids are heavier then liquids.
Do powders have to go in a clear bag when going through airport security?
Yes, powders must be placed in a clear, resealable plastic bag when going through airport security.
Can you bring powders on a plane in your carry-on luggage?
Yes, you can bring powders on a plane in your carry-on luggage, but they must be in containers that are 3.4 ounces or less and placed in a clear, quart-sized plastic bag.
Can you take powders on a plane in your carry-on luggage?
Yes, you can take powders on a plane in your carry-on luggage, but they must be in containers of 12 ounces or less and placed in a clear, resealable plastic bag for security screening.
Which chemicals are placed at the bottom of the periodic table?
Actinides
What is a spotting tile used for?
It is used for Science experiments using chemicals. The dents in the spotting tile are where the chemicals are placed for examination.
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 does rails do?
help you keep your balance. usually placed in stairways.
How far in should table legs be placed for optimal stability and balance?
Table legs should be placed approximately one-fourth of the total length of the table in from the edges for optimal stability and balance.
What is the function of top loading balance?
A top loading balance is used to accurately measure the mass of an object placed on its weighing pan. It is widely used in laboratories for tasks such as weighing chemicals, samples, or other materials with precision. Top loading balances have a higher weight capacity compared to analytical balances, making them suitable for larger samples.
