hey wats froth flotation ??
my previous thread is EPICLY WRONG!
this is what i got!! :D
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in several processing industries. Historically this was first used in the mining industry.

wrong answer aayega phir .. anyways mein samjha burette saaf kar rahay hain!!! ye tu flask saaf horaha hai :D

B hi sahi answer hoga ..

Tap water say karo gay pahlay .. phir distilled water say ..

Agar ending mein Acid daal diya .. tu Alkali already react hojayega thora sa .. aur kam acid chahiye hoga reaction kay liye .. aur incorrect results aayeingay ..

Agar ending mein Alkali daal diya .. tu Alkali ka amount barh jaayega .. aur ziyada acid chahiyee hoga reaction kay liye .. aur incorrect results aayeingay!!!
