Identify the salts P and Q from the observations given below:
On performing the flame test salt P produces a lilac coloured flame and its solution gives a white precipitate with silver nitrate solution, which is soluble in Ammonium hydroxide solution.
State your observations when Barium chloride solution is mixed with Sodium Sulphate 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.
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:
\[\ce{ZnSO4 ->[A]Zn(OH)2->[B]Na2ZnO2}\]
A given white crystalline salt was tested as follows:
A flame test on the salt gave a persistent golden-yellow colourisation. What conclusions can be drawn for the observation?
When an ammonium salt is warmed with sodium hydroxide solution, a gas is evolved. State three ways in which you could identify this gas.
An amphoteric oxide.
Write balanced equation for a metal that evolves a gas which burns with a pop sound when boiled with alkali solutions.
