BIOCHEMISTRY

colloid

tiny particles dispersed in something else, stable and won’t settle, but not truly dissolved.

emulsoid

“Solvent-loving” → have affinity for water, form gels (e.g., gelatin).

suspensoid

“Solvent-fearing” → no affinity for water, unstable without stabilizers (e.g., ferric hydroxide).

what happen to the ferric chloride when added to boiling water?

emulsoid

where as it requires a lot of drop of saturated ammonium to form rpecipitate

suspensoid

requires few drop of saturated ammonia to form precipitate
