Why is Barium Sulphate used in the limit test for sulphates?
Barium sulfate is very sparingly soluble. Any addition of it to a solution containing sulfate or barium will almost immediately cause a precipitate to form.
Why you use BaSO4 reagent instead of BaCl2 solution in limit test of sulphate?
BaSO4 is insolubel AND it contains sulfate, the ion of which the absence or existance should be tested for. (This doesn't sound quite logic)
Why do you add mercuric sulfate in COD test?
Mercuric sulfate is added to complex chloride (and other halogen) ions. These ions interfere in the COD digestion by complexing with the silver to reduce its catalytic effect and by reacting with the dichromate to form elemental halogens thus giving falsely high readings.
What are sodium hydroxide and copper sulfate used to test for?
protiens
How do geologists test limestone?
they splash dilute acid on it. It will dissolve (very bubbly when it does)
How to tested Chloride and Sulfate limit test By USP monograph?
u can find the limit test for chloride& sulphate in a pharmaceutical chemistry by baccket or chatwal
What do you observe when dilute HCl is added to Na2CO3 in a test tube?
nothing happens..........
What happens when zinc is added to dilute sulfuric acid in a test tube?
nothing happens
Why is it that when iron is added to dilute acid the test tube turns hot?
Because there's a chemical reaction going on.

How would you test the presence of sulfate ions?
To identify the presence of sulfate ions in a solution, follow these steps: To acidify the sample, add a few drops of dilute hydrochloric acid (HCl) to the sample. Then, add a few drops of dilute barium chloride (BaCl2) solution to the sample. If sulfate ions are present in the solution, a white precipitate of barium sulfate (BaSO4) will form. The reaction is: Ba²⁺ (aq) + SO4²⁻ (aq) → BaSO4 (s) For example, if we have a solution of magnesium sulfate (MgSO4), the reaction would be: BaCl2 (aq) + MgSO4 (aq) → BaSO4 (s) + MgCl2 (aq) By observing the formation of the white precipitate, we can confirm the presence of sulfate ions in the sample.
Will water dilute an etg test?
Water can dilute an ETG test. However, you will have to drink a large amount of water for the dilution process.
A test that can be used to determine whether a solution has potassium sulfate?
Potassium by flame-ionisation color test: redish purple Sulfate: by Barium chloride suspension test ( BaSO4)solid
Why you use BaSO4 reagent instead of BaCl2 solution in limit test of sulphate?
BaSO4 is insolubel AND it contains sulfate, the ion of which the absence or existance should be tested for. (This doesn't sound quite logic)
How can you test strontium nitrate ammonium carbonate and potassium sulfate?
A flame test.
How much is15 mg of morphine sulfate on a drug test?
Enough to test positive
What is the effect on zinc granules when added to dilute sulphuric acid?
the test tube which holds the zinc becomes hot , the zinc turns into zinc chloride and hydrogen gas is produced. It is a chemical change.
