Analytical chemistry is a chemistry field that aims to isolate, specify, and quantify matter. Several methods are used to isolate matter into its constituents in this area. Identifying methods are used to differentiate with other matters. The final is quantifying the quantity using numerals....
Why is HBr/KBr not a buffer solution? What are some common misconceptions or mistakes involving buffers? Briefly explain your answer. What effect does buffer volume have on the total buffer capacity? Explain. Which of the following solutions can act as a buffer? (a) KCl/HCl (b) KHSO_{4...
What is the molar mass of Barium? Atomic Mass and Molar Mass The periodic table lists the atomic mass and molar mass of each element. The values are the same, but their units are different. Atomic mass has the units atomic-mass-units, or AMU. Molar mass is the mass of one mole of ...
What is the molar mass of sucrose? Calculating the Molar Mass of a Compound: In order to calculate the molar mass of any compound, we only need to know what elements are contained in the compound and what the molar mass of the elements are. ...

Br2 + 2KI —— 2KBr + I2 Similarly, when Bromine is added to a solution of Potassium Iodide, it replaces the position of Iodine in the compound. As a result, Potassium Bromide is formed, whereas a molecule of Iodine is given out. This reaction takes place because Bromine is more reac...

The difference is that, if you take the colourless material and alter its physical structure without any change to its chemical structure, you can see that it's colourless. In chemistry, we'd want to now its true colour when not masked by its temporary crystalline structure. Jul 24, 2011...
The polydispersity value for a standard PEG-1000 sample, as determined by vapor-phase osmometry, is achieved at probe distances of 5.4, 7.2, and 8.2 cm, respectively, when different salts, KF, KBr, and KI, are mixed with the polymer. All data are consistent with an ionization mechanism in...
Fermented crackers, soda crackers withstand humidity in similar way The synthetic urine contained urea (11.5 g/L), glycine (2.87 g/L), KHC[O.sub.3] (13.8 g/L), KCl (2.49 g/L), KBr (4.0 g/L), and K2SO4 (1.36 g/L), and had the same total N content as the cow urine (5.92...
