How do i get a small bit of water out of my bath?

A sponge can be rang out you know? Failing that use towels.

The sink unblocker liquid can be squeezed right into the sink even if there is water the solution sinks down to the blockage.. how do you think it works overwise!?

In all likelyness hair and maybe even poo/sperm particles it being a student house are probably blocking the hole. Man up and grab them out with your fingers! Use the sink plug as a mini plunger, press the sink plug down then rapidly press in and out.

Fail to see what the problem is... jesus!

And you can buy this stuff pure?

If I recall correctly, the stuff you can buy from ordinary shops at about a pound a kilo is ~99%. Maybe it's just more expensive to get 100%, maybe the ~1% is anti-caking agents or something like that.

here, for example, is a hazard sheet for caustic soda, written for a chemistry lab:

Here's the overview from it:

It makes bleach look like Ribena. If you want to get an idea of that scale, drop a cupful into water and see what they mean by a moderate reaction. Or find a video of it. One with a thermometer would be good - the amount of heat generated is quite impressive.

It can be used to dissolve bodies. It can burn your skin enough for you to need skin grafts, or enough to kill you. If you mix it with other cleaning products, it can give off a fair bit of chlorine gas, enough to kill you.

A cupful of it neat is a hell of a lot and you might well want to be more cautious with it. If you have it in a lab, it has to be kept in a locked cupboard and handled only by authorised staff wearing protective clothing, goggles and gloves.

Commercial drain unblockers based on caustic soda are usually less than a 5% solution. The pure stuff is properly dangerous.

There's no chlorine in caustic soda, it's NaOH. Mix it with bleach, which would be pretty stupid, and the bleach may give off chlorine. It turns fats into soap, so basically dissolves deposits of fat, skin and hair which are stuck in your pipes.

I have appalling plumbing here with too small pipes and not enough drop so my bath blocks all the time. Maybe once a month I tip some caustic soda down the drain. A cupful is maybe a bit keen but I stick about maybe 150-200g down at a time. You could dissolve it but if there's standing water it won't get through before it's too diluted. The crystals will drop straight through the water to the bottom of the trap and dissolve in their own time, clearing the blockage at the same time.

Unlike sulphuric acid, which is commonly what plumbers use, it doesn't stink the place out with a nasty eggy smell and it won't destroy your plumbing.
