How khổng lồ distinguish between NaHSO4 và Na2SO4 in lab using these reactants in this table?I looked up every reaction online, nothing helps!! please give me a hint.we can only use our eyes lớn know the difference between the two colorless tubes using these reactants in table.for instance if i use bacl2 , they will both size white percipitate which doesnt help...etc.

What vị you know about khổng lồ detect sulfates?You found BaCl2. Great. So you know both are sulfates. What does it mean if a salt contain hydrogenatoms regarding pH?Which of the substances could be used if something is acidic?Answer this questions, by the way we vị not solve homeworks, without your own atempt.
they both contain sulfates tho so bacl2 wont work as i mentioned. This is not homework sir, i know the site rules, im trying to help someone solving this question, i gave my try for the first reactant, i tried to lớn see the products of them all.I dont want you to lớn solve anything for me, thanks
I changed a little bit the answer above. But anyway, why the other one dont vì chưng the work by him/her self.
I dont understand, what is the problem of me helping someone? i spend most of my time helping people và sometimes i get help from this great site.we can only use eyes, so indicators dont work, for instance if i use NaOH, both solution will stay colorless.
You can use your eyes, there is one substances what change dramatically if you địa chỉ it, which could it be?This one is also used in the kitchen.
you mentioned in your hint the acidic compound so i think your talking about adding a base, is there another base than NaOH?kitchen... Baking soda?i appreciate your help btw.

NaOH doesnt help because no indicator present.Yes correct baking soda.. Which one is the baking soda here? bởi vì you know effervescent powder? What happens if you add the compound khổng lồ the hydrogensulfat.
If I have two tubes with two sulfates, how should it help if I look up the K2 values of carbonic acid và sulfuric acid. If I find them in a table how to lớn go further..

This is a rather strange statement, plenty of pH indicators that work by changing colors. They are not lsited between substances that can be used, but pH strip would be my tool of choice here.

You don't have two tubes with two sulfates, you have a tube with a sulfate và a tube with hydrogensulfate.
