Question

Blood is composed of many tiny cells in a liquid called plasma. Blood is actually considered a colloid. The dispersed state of matter is , and the dispersion medium is .
Fruit jelly is mostly juice, but it doesn’t run all over the place even if you cut a piece and put it on a plate. This is because the juice is contained within the structure of a natural substance called pectin, which can hold its shape on its own at room temperature. The dispersed state of matter is , and the dispersion medium is .

Answer 1

Answer:

In blood: Disperse phase : blood cell ; Dispersed medium : liquid plasme

In fruit jelly: Disperse phase : Fruit juice ; Dispersed medium : Pectin

Explanation:

Dispersion phase is defined as  phase in which is present or scattered into another phase as colloidal particle is called dispersion phase.

The medium in which dispersed phase is present is called dispersed medium.

So, in a blood, tiny cells are the colloidal particles are dispersed phase which are present in the liquid medium called plasma.

The dispersed phase in fruit jelly is fruit juice is present as liquid in a pectin which is dispersed medium. Whereas pectin is in solid state

Answer 2

Q 1. For blood, the dispersed state of matter is solid and the dispersion medium is liquid.

Explanation- Blood is a colloidal solution with partial behavior of suspension. In blood hormones, respiratory gases, RBC, WBC, platelets, proteins, digested food etc are present in dispersed medium (plasma). Due to its colloidal nature, it becomes flocculated and plasma is separated from other compounds in hospital by special devices.

Q 2. For fruit jelly, the dispersed state of matter is liquid and the dispersion medium is solid.

Explanation- Pectin in fruit jelly provide three dimensional structure to the jelly and that is the region behind its solid look. Yes, fruit jelly is a colloid, in which bits of sweetened fruit sit suspended in water and a thickener called pectin.
