Why is starch solution used as indicator in Sodium thiosulphate Iodine titrations instead of phenolphthalein indicator?
Phenolphthalein is an acid base indicator - it does not show the end-point in a thiosulfate type titration. Starch gives a very sharp end-point from a blue-black to colorless end-point when titrating iodine with thiosulfate. Phenolphthalein would just not detect this change.

How many chloride ions are in sodium chloride?
Well...depends who you ask :P. I guess two. Sodium Chloride is NaCl. It's an "ionic compound" which means the atoms are not covalently bonded, they actually exist as Na+ and Cl-. At this point, it's worth mentioning that an ion is any charged species. Positive or negative, they're both ions. The reason it's a bone of contention is because bonding is not black and white. Covalent or ionic...it's a sliding scale and you can't just say where one begins and the other ends. That said, it is widely accepted that NaCl is a highly ionic bond.
