Reaction of sodium phosphate and ammonium sulphate
« on: July 16, 2004, 09:25:43 PM »
In the experiment, there is no observable change when sodium phosphate is added to ammonium sulphate. I only know both of them are very soluable in water. how can I tell there is a reaction or not?

Can anyone tell me if there is a double replacement reaction or there is no reaction?

thanks.

both salts are water-soluble. they won't react with each other. instead, they dissolve to form a solution containng aq sodium, ammonium, sulphate & phosphate ions.

Today I discussed with my classmate and one of them told me :

sodium phosphate is added to ammonium sulphate react to form ammonium phosphate and sodium sulphate and then dissolved in water again. once they form , they dissolved in water . therefore the reaction is not noticeable.

Is she correct?
