Which is NOT a feature of a colloidal suspension: Not easily filtered particles

Question

Which is NOT a feature of a colloidal suspension: Not easily filtered particles can be visually distinguished Does not tend to settle scatters visible radiation How does an End point differ from an equivalence point? It doesn't, the two are synonymous Equivalence point occur when half the analyte is consumed in a titration End point occurs when a physical change occurs to represent chemical equivalence End point is the upper limit of pH detectable by an indicator A known volume of reagent of known concentration (in excess) is allowed to react with a analyte. The remaining reagent is then reacted to determine how much is left. This process is called A back titration An argentometric titration a standard titration A potentiometer titration

Explanation / Answer

Colloidal suspension is also known as collidal solution:

A The particles in the collidal suspension cannot be easily filtered.

B. Particles are not visually distinguished

So 2 is the option

(Q.2)

End point : It is the point where color change (physical change) occurs in the titration.

Equivalence point: It is exact point where the amount of titrant = amount of analyte (it is a theoritical value).

So answer is option C

Q.3)

Standard titration: analyte of known concentration with a fixed volume is titrated with a titrant of known concentratin and volume.

But in back titration excess reagent or titrant is reacted with analyte and remaining titrant is further analyzed. So it is called back titration.

A is the correct option
