Block diagram of atomic fluorescence spectrometry:
The instrumentation for AFS consists of atom reservoir that might be a flame or a furnace etc., a basic source emitting the features absorption radiation of the element being determined, a monochromator (or filter), detector, signal processor and readout device. The basic source is commonly a hollow cathode lamp or a tuned laser. The block figure of the equipment required for AFS is shown below:
Charectaristic of covalent bond
20ml of water sample requires 15ml of 0.1mg/l sodium carbonate using phenolphthalein indicator. state the type of acidity and calculate the acidity
thermoplastics
discuss the concentration of cations in the solution copper sulphate and zinc sulphate
Q. Define Alcoholic Acidity? Alcoholic acidity is defined as mg of H 2 SO 4 required for 100 g of the sample to have the same alcohol soluble acids. Grains or their milled
why boron shows +3 as well as-3 oxidation states?
How much time a hydrogen electron will take when it goes from first orbit to second orbit?
Q. Show Bond Lengths and p Π - d Π bonding? The bonds between S and 0 are much shorter than expected for a single bond in its oxides and therefore, may be considered as doubl
Electron enters the sub-shell for which (n+l) value is minimum. This is enunciated as: (1) Hund's rule (2) Aufbau principle (3) Heisenberg uncertainty principle (4) P
