State your observations when Barium chloride solution is mixed with Sodium Sulphate Solution.
State your observation When excess sodium hydroxide is added to calcium nitrate solution
Name a solution that will separate the component of the following mixture: Zn(OH)2 from Pb(OH)2
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.
How will the action of dilute hydrochloric acid on sodium carbonate and sodium sulphite enables you to distinguish between these two compounds?
Sodium hydroxide solution is added first in a small quantity, then in excess to the aqueous salt solutions of copper (II) sulphate, zinc nitrate, lead nitrate, calcium chloride and iron (III) sulphate. Copy the following table and write the colour of the precipitate in (i) to (v) and the nature of the precipiatate (soluble or insoluble) in (vi) to (x)
| Aqueous salt Solution | Colour of Participitate when NaOH is added in a samll quantity | Nature of precipitate(soluble or insoluble) when NaOH added in excess |
| Copper (II) Solution | ||
| Zinc nitrate | ||
| Lead nitrate | ||
| Calcium chloride | ||
| Iron(III) sulphate |
Write balanced equation for a coloured metallic oxide which dissolves in alkalis to yield colourless solutions.
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?
