# Subsitution of Burette for Titration

## Recommended Posts

I've been waiting to do titration with a standard solution of HCl to determine the concentration of anhydrous ammonia.

Would there be a substitute I could use without a Burette for accurate readings?

The one possible choice that I've figured was to manually drop the titrant from a beaker until endpoint but I'm not sure if it would be accurate enough.

Does anyone know of any other possible way's to carry out titration without a Burette and being as accurate as possible to a real Burette?

Thanks

PS. Burette's are too expensive for me to buy at this time and the concentration of HCl is 0.15 mol/L.

why would you do a titration of anhydrous ammonia? Anhydrous by definition means that it is free of water, and therefore must be 100%...

Or am I misunderstanding your experiment?

I'm hoping he means aqueous ammonia...

I was thinking of calibrating the pipette by measuring 5mL of water in a graduated cylinder then sucking the fluid through my pipette and mark the bottom of the Meniscus as 5mL. Then continue doing with 10mL and 15mL and so on.

That is not very precise, is it? You will add two sources of error into your system.

Do you have a balance? Even one of the cheap ebay ones will give you 0.1g resolution. You can use that to calibrate volumetric glassware (not to ISO standards but, better than a typical measuring cylinder).

I have a two decimal place scale, I will try this method and see what I get.

Thanks for the help.
