- Which substance gives a different flame colouration from the others?
- The most soluble compound in water is:
- Na_2SO_3 and NaHCO_3 may be distinguished by treating their aqueous solution with:
- Addition of excess of sodium hydroxide solution to a solution of nickel sulphate results in the formation of a:
- A and B are two salts. A with dilute HCl and B with conc. H_2SO_4 react to give reddish brown vapours, hence A and B respectively...
- The compound which is insoluble in hot water and NH₃ is:

- Borax bead test is not given by:
- On adding ammonium hydroxide solution to Al_2(SO_4)_3 (aq):
- Aqueous ammonia is used as a precipitating reagent for Al^ 3+ ions as Al(OH)_3 rather than aqueous NaOH, because:
- An aqueous solution of a substance gives a white precipitate on treatment with dil. HCl, which dissolves on heating. On passing...
