salt preparation help in chem!

[Dean713]

can some1 plz xplain the different methods of salt preparation in detailed but a simple form? :mrgreen:

 

[SuperXDE]

acid + alkali → metal salt + water
HCl + NaOH → NaCl + H2O
acid + metal → metal salt + hydrogen
2 HCl + Mg → MgCl2 + H2
acid + metal oxide → metal salt + water
2 HCO2H + MgO → Mg(HCO2)2 + H2O
acid + ammonia → ammonia salt
HF + NH3 → NH4F

Neutralisation Copied from Wikipedia btw.

wat about titration and direct combination? i was lookin more for an explanation....

Poeple you coining now to study such important things
will any wya here it is

Preparation of souble salts....
Acid and base used are in solution form Eg HCl
(1) a known volume of acidis pipetted onto a conical flask and 2 or 3 drop of indicator is added.
(2) the base is added from the burette until indicator changes colour. this means all the acid has been neutralised from salt and water
(3) repeat the above steps after noting the end points but without adding indicator
(4) the solution is transferred to be an evaporting dish and heated to partially evaporatethw water till crystallization point.
(5) cool and filter out the crystals and dry between the fold of filter paper..

soulble slat by titration ( not hydrated or a nitarte salt )...
reapeat the above steps till point 3 then write
(4) the solution is transferred to as evaporting sidh and heated to completely the water till dry crystalls are left behined

souble salt by meatl oxide and acid solution ( hydrated or nitrate or any crystall )
1 crush metal oxide and add to the acid in exess with constant stirring
2 filrter out the excess meatl oxide solid
3 heat the soultion till point off crytalisation.
4 cool and firlter out the crustals.
5 dry the crystals between the fold of filter paper.

2 filter out the excess meatl oxide soild.
3 the solution is transferred to an evaporting dish and heated to copletely evaporate the water till dry crystals are left behind

Inssoulbe salt from 2 solutions Eg Lead II sulphate
1 Mix lead II suplhate and H2SO4 in a beaker and stirr
2 filrter out the residue ( slat )
3 heat the slat ( residue ) till complete dryness..
and thats all folks bro
'sorry for writting the first process twice as Xtreme papers is laggin
