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 primary purpose of substantive analytical procedures?
the primary purpose of substantive analytical procedures is to provide evidence as to the validity of an account balance.
What are measuring apparatus in analytical chemistry?
Examples: analytical balance, spectrophotometer, titrimeter, coulometer, emission spectrometer etc.
Can you give 3 pieces of equipment used in laboratory measuring?
A measuring cylinder, a balance and a burette.
Is beaker used in measuring exactly 15 g salt?
You need an analytical balance and a small beaker.
Significance of electronics in analytical chemistry?
Electronics play a significant role in analytical chemistry. A digital electronic analyticalÊ balance is used to measure the mass of an object. Electronics are also used to count and move electrons.
Does a trial balance determine the accuracy of the numbers?
No a trial balance does not determine the accuracy of numbers. It only tests the accuracy, if done right.
What limits the accuracy of inertial balance?
The accuracy to which you can take into account the mass of the spring, and the accuracy and consistency of spring tension data inherently limit the accuracy of an inertial balance.
Is trial balance merely a proof of arithmetical accuracy explain the errors which are not disclosed by a trial balance?
No, it is not a complete proof of arithmetical accuracy of account. A Trial Balance in which the credit and debit accounts match does not prove that, all transactions have been recorded in the proper accounts. For example, the wages paid for the installation of machinery had been erroneously recorded by debiting the wages account in the place of machinery account, the Trial Balance would still agree. Similarly, an agreed Trial Balance does not prove that all transactions have been recorded in the books of original entry. For example, a credit sale invoice were to be completely omitted from being recorded in the sales day book, the error would not be disclosed in the Trial Balance. To conclude, we can say that a trial balance should not be recorded as a conclusive proof of the correctness of the books of account.
Who can you donate an analytical balance to It is probably 60 years old?
Any high school would be happy to have a true analytical balance! They are so expensive!
How do you weigh .0001g or less?

Uses of analytic balance?
An analytical balance is used to measure mass to a very high degree of precision and accuracy. The weighing pan(s) of a high precision (.01 mg or better) analytical balance are inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation. The use of a vented balance safety enclosure, which has uniquely designed acrylic airfoils, allows a smooth turbulence-free airflow that prevents balance fluctuation and the weighing of mass down to 1 μg without fluctuations or loss of product. Also, the sample must be at room temperature to prevent natural convection from forming air currents inside the enclosure, affecting the weighing. Analytical precision is achieved by maintaining a constant load on the balance beam, by subtracting mass on the same side of the beam to which the sample is added. The final balance is achieved by using a small spring force rather than subtracting fixed weights.
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.

Which balances is affected by the local force of gravity is it beam or analytical or spring balance?
spring balance
Can you find the mass of a crystal?
Ye, using an analytical balance.
