_____________ (AgCl / PbCl2), a white precipitate is soluble in excess NH4OH
State your observation When excess sodium hydroxide is added to calcium nitrate solution
Sodium hydroxide solution can be used to distinguish between i. iron (II) sulphate solution and (ii) iron (III) sulphate solution; because these solutions give different coloured precipitates with sodium hydroxide solution. Give the colour of the precipitate formed with each of the solution.
State the colour of the residue formed when nitrates of :
1. Calcium
2. Zinc
3. Lead
4. Copper are strongly heat
What do you understand by amphoteric oxide?
Give the balanced equations for the reaction with two different amphoteric oxides with a caustic alkali.
Write a balanced equation for the following conversion:
\[\ce{CuSO4 ->[A]Cu(OH)2 ->[B] [Cu(NH3)4]SO4}\]
A given white crystalline salt was tested as follows:
The addition of barium chloride solution into this solution gave a white precipitate. What conclusions can be drawn for the observation?
Write a balanced equation of a coloured metallic oxide which dissolves in alkalis to yield colourless solutions.
Which of the following about oxides is correct?
