Replacement Titration: In this method the metal, which is to be analyzed, displaces
quantitatively the metal from the complex. When direct or back titrations do not give sharp
end points, the metal may be determined by the displacement of an equivalent amount of Mg
or Zn from a less stable EDTA complex.
Mn+2 + Mg EDTA---> 2 Mg+2 + Mn EDTA-2
Mn displaces Mg from Mn EDTA solution. The freed Mg metal is then directly titrated with
a standard EDTA solution. In this method, excess quantity of Mg EDTA chelate is added to
Mn solution. Mn quantitatively displaces Mg from Mg EDTA chelate. This displacement
takes place because Mn forms a more stable complex with EDTA. By this method Ca, Pb,
Hg may be determined using Eriochrome blackT indicator.
What else can I help you with?
Why using phosphate buffer and magnesium sulphate and calcium chloride and ferric chloride for dilution water in BOD5 test?
Phosphate buffer helps maintain the pH of the dilution water, which is crucial for proper bacterial activity in the BOD5 test. Magnesium sulfate, calcium chloride, and ferric chloride provide essential nutrients for the bacteria to thrive and efficiently break down organic matter during the test. These chemicals help create an environment that supports the growth and metabolic activity of the microorganisms responsible for oxygen consumption in the BOD5 test.
Would calcium nitrate and magnesium react?
Calcium nitrate and magnesium will not react since calcium is more reactive than magnesium and so, magnesium does not displace calcium (See Reactivity Series). However, if Calcium nitrate is in aqueous solution (dissolved in water), some bubbles may be seen when Magnesium is added to it, since the Magnesium would be reacting with the water and producing hydrogen bubbles.
Saturated solution of calcium hydroxide is added to a solution of magnesium chloride?
A white precipitate of magnesium hydroxide forms because calcium hydroxide reacts with magnesium chloride to form magnesium hydroxide and calcium chloride. This is a double displacement reaction where ions from the two compounds switch partners.
What acid will you use to make magnesium sulphate?
To make magnesium sulfate, you would use sulfuric acid (H2SO4) and magnesium carbonate (MgCO3) as the starting materials. When sulfuric acid is added to magnesium carbonate, it will react to form magnesium sulfate, carbon dioxide, and water.
What would happen if you added iron to a solution of magnesium sulphate?
If you add iron to a solution of magnesium sulfate, a displacement reaction would occur, where the iron would displace the magnesium in the sulfate compound. This would result in the formation of iron sulfate and magnesium metal.
Chemical reaction between calcium and copper sulphate?
When calcium metal is added to a solution of copper sulfate, a single displacement reaction occurs. The more reactive calcium displaces the less reactive copper from the copper sulfate solution. This results in the formation of calcium sulfate and elemental copper. The balanced chemical equation for this reaction is: Ca + CuSO4 -> CaSO4 + Cu.

What carbonate is in table salt?
Calcium and magnesium carbonates are sometimes added as anticaking agents.
Would a chemical reaction occur if calcium is added to magnesium chloride?
Any reaction occur.

Copper sulphate add to sodium hydroxide result colour?
When copper sulfate is added to sodium hydroxide, a blue precipitate of copper hydroxide is formed. The color change observed is from the initial blue color of copper sulfate to the blue precipitate of copper hydroxide.
What would you see if you dropped a piece of magnesium ribbon into some copper sulphate solution in a test tube?
If you drop a piece of magnesium ribbon into copper sulphate solution, you would observe a redox reaction where the magnesium displaces the copper in the solution. This results in the formation of copper metal and magnesium sulphate, with a color change from blue to colorless as the reaction progresses. Additionally, there may be bubbling and fizzing observed as the reaction occurs.
Does copper sulphate dissolve in oil?
No. All metal sulphate are soluble in water, except barium sulphate, calcium sulphate and lead sulphate.
What happens when you add zinc to magnesium sulphate?
You create magnesium sulfate and zinc through single discplacement/replacement.Zinc sulfate(aq) + Magnesium (s)->Magnesium sulfate + Zinc (s)ZnSO4(aq)+ Mg (s) -> MgSO4 + Zn(s)Hope it helps ;)
