Titrations

Titrations are used to measure the concentration of an unknown solution using a known solution while tallying the volumes. Several types of these include acid-base titrations, red-ox titrations, colorimetric titrations and gravimetric titrations.

Titration equation can be solved by following the steps below: 1. write a well balanced equation. 2. Calculate number of moles of standard solution that is in the solution. 3. User molar relationship to convert moles of standard solution to that of unknown solution. 4. Find the number of moles of unknown solution.

What is non aqueous titration?

Asked by Wiki User

Nonaqueous titration is the titration of substances dissolved in nonaqueous solvents. It is the most common titrimetric procedure used in pharmacopoeial assays and serves a double purpose: it is suitable for the titration of very weak acids and very weak bases, and it provides a solvent.

Why do we heat KSCN Fe solution befor titration with EDTA?

We usually heat KSCN Fe solution before titration with EDTA so as to produce crystalline crust forms.

Why the conical flask placed on a piece of white paper in titration?

Erlenmeyer Flasks are graduated, meaning they have calibrated lines to help detect the level the solution reaches, much like a graduated cylinder does. Knowing the relative level is important during titrations because they are usually done over many many times and its good to know when the change will take place approximately. But then again burrettes also have calibrated line which are much more accurate.

Basically I think it boils down to the idea that a flat bottomed flask is less likely to tip over than a round bottomed, volumetric one.

So why not just use a beaker? Well probably to avoid from any solution bouncing out as the drops fall into the solvent. A beaker just has a much larger opening at the top.

Regardless though, its convention in the chemistry community.

Are titrations endothermic or exothermic?

In thermometric titration the reaction enthalpy is used to follow the chemical reaction. I guess it dépends on the titration reaction it can be exothermic or endothermic. ΔHr (molar heat of reaction) negative (indicating an exothermic reaction) or positive (indicating an endothermic reaction
