In estimation of copper and nickel why we are using volumetric for copper and gravimetric for nickel seperately?
It is simply because they could not be found together!! copper can be estimated by treating with potassium iodide and iodine will be liberated in the reaction which is titrated against sodium thiosulphate during the reaction we will add sulphuric acid to prevent the hydrolysis of copper sulphate and we follow by, adding ammonia to neutralize sulphuric as it may hinder the reation between iodide and copper!! now again we will add acetic acid to neutralize ammonia.. and the indicator is added at the last because it will get absorbed with the iodine!! now atlast we add ammonium, thiocyanate to prevent the excess of iodine getting added to copper iodide. end point is disappearance of blue color.
Why is AgNO3 used as the precipitating agent in determining the chloride?
It forms a precipitate with chloride:Ag+aq + Cl-aq --> AgCl precip.solidBecause silver chloride (AgCl) is formed as a result of the reaction; silver chloride is very insoluble, an important quality for gravimetric analysis.
What is the meaning of microscopic hair analysis?
Microscopic hair analysis is the examination of hair samples under a microscope to determine characteristics such as color, shape, thickness, and abnormalities. This analysis can be used in forensic investigations to link individuals to a crime scene or to identify potential suspects. However, it is important to note that hair analysis has limitations and should be used in conjunction with other forms of evidence.
Why nickel forms complex with DMG to give bright red precipitate only in colorimetric or gravimetric estimation of nickel?
Because,(i) Ni(II) have d8 electronic configuration, which strongly favors square-planar complex formation;and dmg on loosing one acidic proton favors the square-planar arrangement makes the formation of [Ni(dmg)] complex favorable (ii) Because d8 configuration is stabilized most in square-planar geometry (due to high CFSE) the formation of complex becomes more favorable which adds to the driving force of the complex formation.
Why ammonium oxalate is added in calcium carbonte solution?
ammonium oxalate is added to calcium carbonate because in the reaction between the two a crystal is formed that contain the Ca+2 ion. This is useful because if you have a sample of sodium carbonate with an unknown molarity you can use the oxalate to extract this calcium and determine what the molarity of the unknown solution was

What is keyfield?
A key field is a field of a database table which forms an identifier for a record. It holds a unique data which distinguishes the record from all the other records in the database.

What distinguishes an isotope from a regular element?
Isotopes are different forms of an element that have the same number of protons but different numbers of neutrons in their nuclei, resulting in different atomic weights. This difference in atomic weight among isotopes is what distinguishes them from a regular element.

Difference between analysis and analytics?
Analysis is the process of breaking down a complex object into its simple forms. However, analytics is the science of analysis whereby statistics, data mining, computer technology, etc... is used in doing analysis. Basically, analysis and analytics perform the same function but in the sense that analytics is the application of science to analysis.
What are the two main forms of Risk Analysis?
There are two main forms of Risk Analysis:1. Qualitative Risk Analysis &2. Quantitative Risk AnalysisQualitative Risk AnalysisThis is used to prioritize risks by estimating the probability of the occurrence of a risk and its impact on the project.Quantitative Risk AnalysisThis is used to perform numerical analysis to estimate the effect of each identified risk on the overall project objectives and deliverables.Usually, you prioritize risks by performing qualitative analysis on them before you perform quantitative analysis. We will learn both one by one in the subsequent chapters.

How many humps dose a n have in cursive?
In cursive writing, the letter "n" has one hump. The loop of the "n" forms a single arch, which distinguishes it from letters like "m," which has two humps.
