hey guys i dont noe if it is a silly q but i want to noe wat is titration ??? ??? ??

WARRIOR:
titration is ued to producce a soluble salte. I.E NACL

SO USE NAOH AND HCL

BUT WE HAVE TO ADD EXACT AMOUNTS OF BOTH OF THEM TO PRODUCE A SALT OF PH7

WHY?

CAZ ITS OLUBLE..HCL  OR NAOH CAN EASILY DISSOLVE IN NACL MAKIN IT ALKALIN OR ACIDIC

SI?

The negative electrode is the cathode, not the anode, since it attracts cations!

Thanks for the lovely tips, man.
