mix a solute and solvent together and it will make a solution Increase the surface area of the solute with a mortar and pestle. Next measure out the mass of the solute. Add water and increase the temperature and use a magnetic stirrer. Do not fill to the necesary volume. Do not use a graduated cylinder instead use a volumetric flask. Pour solution into the flask. First measure the mass of the flask. rinse the beaker in which the solution was in. add more water to flask and fill to the needed volume. Then find the mass of solution.
• Complexometric titration is a type of
titration based on complex formation
between the analyte and titrant.
• Complexometric titrations are particularly
useful for determination of a mixture of
different metal ions in solution. An
indicator with a marked color change is
usually used to detect the end-point of the
titration.
Standard Solution is a solution that the concentration of which is accurately known
Dissolve a known amount of potassium permanganate in a known volume of demineralized water; calculate the concentration of manganese in the solution.
screw u
A solution that has been titrated against a primary standard solution.
A solution is a homogenous mixture of two or more substances. while A solution whose concentration is known is called a standard solution.
Standard Solution is a solution that the concentration of which is accurately known
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.
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.........
Standard solution
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.
Dissolve a known amount of potassium permanganate in a known volume of demineralized water; calculate the concentration of manganese in the solution.
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.

it is primary standard........ but before making solution dry it at 120. C
