What is meanings of AR and GR in chemical grade?
AR grade means Analytical grade it is highly pure or enough pure to carreid out any analytical test at the same time GR is stands for Guarnted reagent which is superior grade to perform any test.
What is the difference between technical grade and commercial grade chemicals?
Technical grade chemicals are less pure than reagent grade chemicals, and are usually used in applications where there are no official standards for impurity levels.Commercial grade chemicals are prepared in volume for general industrial use. Purity levels vary but they're often comparable in purity to technical grade chemicals.

AR is analytical reagent and LR laboratory reagent; practically differences are not significant and depends on the reagents company.
What is meaning of excelaR in chemical grade?
I think it is same as GR (guaranted reagent) reagent.
What is LR or AR grade chemicals?
The laboratory reagent grade are specified according to their purity. The common commercial grades of reagents are as follows.. AR- analytical reagent grade OR-organic reagent IP - pharmaceutical reagent grade LR- laboratory grade CP- Chemically pure

Are sigma online training classes free?
There are numerous website that offer sigma training online. However, most of them does not offer it for free no matter how old you are or what grade you are in.
What is used to purify the reagent grade solid chemicals?
Recrystallization, most likely. This takes advantage of the product and contaminates differences in solubility.
Why are compounds called pure substances?
A pure substance is a compound (or element) with very low concentrations of impurities. They have many names, after the use: pure, ultrapure, for spectroscopic, for chromatography, electronic grade, nuclear grade, for analysis, reagent grade, etc.
How much does magnesium cost per gram?
The cost of Magnesium per pound is $2.45 per pound. The price will vary depending upon the purity and the form of the magnesium required, and the quantity being purchased, (as buying in bulk tends to result in a lower price for a given mass of product). The chemical supplier Sigma Aldrich will give prices for various forms of magnesium and in various quantities. As an example: 500g of granular, reagent grade, 98% pure magnesium would cost £43 (GBP) 2kg of granular, reagent grade, 98% pure magnesium would cost £144.10 (GBP)
what is the unit of purity of a chemical sustance?
If you are referring to chemical purity by grade, I suggest you research the following terms: ACS Grade (American Chemical Society) - highest level of purity Reagent grade - Almost as stringent as ACS USP Grade - Equivalent to ACS for many drugs NF Grade (National Formulary) - Equivalent to ACS for many drugs Laboratory Grade Purified Grade Technical Grade
What is the difference between technical grade and commercial grade chemicals?
