i have three beakers each have diff %of HCL .....how i can find that which one is 30%of HCl, which one is 200%of HCl and which one is 10%of HCl.

 

 

 

plz help me to find it

 

 

my basic aim is to find the HCL %

Have you ever done an acid/base titration before?

no

acid base titrations are a fairly simple tool you can use to tell the molarity of a HCl solution. There are plenty of articles online that can walk you through it.

 

Here are a few:

Titration will be your best option. While they can be a little fiddley to do at first, you will soon get the hang on it and you'l be fine. The important thing is to be as accurate as you can...the more accurate you are, the better results you get (i.e. get the conentration of acid closer to whats its supposed to be!) Remember also, that you only ever need a very small amount of whichever indicator your going to use....if you use too much, then it is often very difficult to see the exact point at which the titration is complet.

I presume the 200% should be 20%

I would measure the density of the three liquids. In this case (as with may others) the denser solution will have the higher concentration.

It's quick, easy and non-destructive.
