Using sodium hydroxide solution, how will you distinguish: Zinc nitrate solution from calcium nitrate solution
Using sodium hydroxide solution, how will you distinguish:
Iron (II) chloride from iron (III) chloride
Three test tubes contain calcium nitrate solution, zinc nitrate solution and lead nitrate solution respectively. Each solution is divided into two portions (i) and (ii). Describe the effect of
- adding sodium hydroxide solution to each portion in turn till it is in excess.
- adding ammonium hydroxide to each portion in turn till it is in excess.
Choose the correct answer from the options given below :
Hydroxide of this metal is soluble is sodium hydroxide solution
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 precipitate (soluble or insoluble) in (vi) to (x).
| Aqueous salt solution | Colour of precipitate when NaOH is added in a small quantity | Nature of precipitate (soluble or insoluble) when NaOH is added in excess |
| Copper (II) sulphate | (i) | (vi) |
| Zinc nitrate | (ii) | (vii) |
| Lead nitrate | (iii) | (viii) |
| Calcium chloride | (iv) | (ix) |
| Iron (III) Sulphate | (v) | (x) |
