What is a standard solution?
Standard Solution is a solution that the concentration of which is accurately known
Will Mn produce ions in a solution?
Yes, manganese has ions in solutions.
Is Mn aqueous?
No, Mn is a transition metal and is typically found in solid form rather than in aqueous solution.
When you calculate the mass of borax needed to make up the standard solution do you include 10H2O?

What is a secondary solution?
A solution that has been titrated against a primary standard solution.
How to make a standard solution?
A known quantity of a substance is dissolved in solution for a standard solution. This is expressed as units of mole per liter, moles per cubic centimeter, or in terms of that particular titration.
What is a standard solution?
Standard Solution is a solution that the concentration of which is accurately known
Why is magnesium sulphate added in the assay of calcium lactate?
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 is a non standard solution please answer definition?
is that solution that is just unlike standard solution .so if any solution dont have the standard property which is called the non standard solution the property of the standard solution is:-1.high purity 2.it is stable toward the air 3.available it means that in the lost cost.........
Will Mn produce ions in a solution?
Yes, manganese has ions in solutions.
A solution of approximate concentration is _ solution?
Standard solution
Is it possible to prepare a standard NaOH solution by dissolving an accurate amount of NaOH pellets in a known volume of water?
you can't make a primay standard solution with NaOh.as NaOh is said to be a secondary standard you have to establish the normality using some primary standard acids.
Is Mn aqueous?
No, Mn is a transition metal and is typically found in solid form rather than in aqueous solution.
What is the reaction of iron sulphate solution with potassium permanganate?
The Mn+7 ions (purple) are reduced to Mn+4 ions (brown), unless some diltue sulfuric acid has been added to the solution. This will make the Mn+7 ions reduce fully to Mn+2 ions (colourless). The end point of the reaction is gotton when there is a permanent pale pink tinge left in the conical flask. (The Potassium Permangante should be in a Burette and be released slowly into the flask containing the Iron Sulfate). HOWEVER: Iron sulfate gets oxidised by Oxygen in air and water and undergoes hydroylisis of water. Therefore you should use a primary standard like Ammonium Iron II sulfate for this reaction.
Difference between primary standard solution and a secondary standard solution in acid-base titration?
primary standard solution is prepared by direct measurements of the mass of solute and the volume of solution.whereas, a secondary standard solution is a solution whose concentration can't be determined directly from weight of solute and volume of solution, the concentration must be determined by analysis of the solution itself.
What is a solution of known concentration called?
Standard solution
When you calculate the mass of borax needed to make up the standard solution do you include 10H2O?
