Hi, could anyone provide me with a recipe for acidified Barium Nitrate? For measuring sulphate in fertiliser.
Thanks.

Re: Acidified Potassium Permanganate
For acidified Potassium permanganate....
.01M of KMnO4 and just added a couple of drops of conc. sulfuric acid
Haven't heard of acidified Barium nitrate

Thanks, sorry I got the subject wrong! Actually after acidified barium sulfate so I've re-posted with the correct subject...been a long day!

Oops I mean Barium nitrate...time I went home!!
Re: Acidified Barium Nitrate
Is it gravimetric? We use 7% barium chloride solution to drop out the sulfate from fertilizer ( it presipitates as barium sulfate)

Re: Acidified Barium Nitrate
We use a saturated solution of Barium chloride.

Re: Acidified Barium Nitrate
From a Chemistry teacher....
acidified Barium chloride is what is needed....... sometimes we use a bit of HCl first to acidify and then add barium chloride.
It will form Barium sulphate precipitate...which is wanted

Acidified Solutions
Yes.
To acidify a solution just means to lower the pH below 7.0 using a slight addition of an appropriate concentrated strong acid. That is all.
The only 'trick' to it is to choose an acid that doesn't form a precipitate with your solution. Usually this simply means to match the acid with the anion. Hydrochloric for a chloride solution, sulfuric for a sulfate, nitric for a nitrate, et cetera.
