Why does the solution decolorize on standing after the equivalence point has been reached?

Chemistry

The equivalence point of a titration is equal to its stoichiometric equivalents of analyte and titrant.

Depending on the concentration of titrant we could be adding little excess of it and this may result in persistence of color of solution. After continuous stirring for a while the excess titrant may react with dissolved CO₂ in air and thus decolorizing the solution.

Answer:

The potassium permanganate slowly fades in color as it is dissolved in the water.

Explanation:

Hello,

Perhaps, your talking about a titration that was carried out by using potassium permanganate as the titrant, thus, bringing to bear the fact that the equivalence point of a titration is equal to its stoichiometric equivalents of analyte and titrant, one could state that as the titration is carried out, the potassium permanganate slowly fades in color as it is dissolved in the water after the equivalence point is reached since the formed species become colorless as well.

Best regards.

Tresset [83]

Out of the options, the best indicator is a color change since it is the only one that can't really be blamed on a physical change.  you will eventually notice that during qualitative labs and some quantitative labs, usually the thing that you are looking for is either color change or the production of a precipitate to indicate the presence of a chemical reaction

What is the density of a cube that has a mass of 25 g in a volume of 125 cm 3
GalinKa [24]

<span>The density of an object is defined to be its mass divided by the volume it occupies. For this problem, the mass of the cube was given to be 25 g while its volume is 125 cm</span>³. Thus, we simply divide 25 g by 125 cm³ to get the object’s density. We then calculate that the cube has a density of 0.2 g/ cm³.
