Identify the salts Q from the observations given below:
When dilute HCl is added to a salt Q, a brisk effervescence is produced and the gas turns lime water milky. When `NH_(4)OH` solution is added to the above mixture (after adding dilute HCl), it produces a white precipitate which is soluble in excess `NH_(4)OH` solution.

Identify the salts P & Q from the observations given below: i] On performing the flame test salt P produces a lilac coloured flame & its solution gives a white precipitate with silver nitrate solution, which is soluble in ammonium hydroxide solution. ii] When dilute HCl is added to a salt Q, a brisk effervescence is produced and the gas turns lime water milky. When NH_4 OH solution is added to the above mixture [after adding dilute HCI], it produces a white precipitate which is soluble in excess NH_4OH solution.

Dilute sulphuric acid will produce a white precipitate when added to a solution of

When NH_(4)Cl is added to a solution of NH_(4)OH :

Identify the cation in each of the following case Sodium hydroxide solution when added to solution C gives bluish white precipitate which is insoluble in excess.

Identify the salts P, Q, R from the observation Salt P has light bluish green colour. On heating, it produces a black coloured residue. Salt P produces brisk effervescence with dil. HCl and the gas evolved turns lime water milky, but no action with acidified potassium dichromate solution.

Identify the cations in each of the following case : NH_(4)OH Solution when added to the Solution (B) gives white ppt which does not dissolve in excess.

Which of the following nitrate salt solution neither produce ppt. with excess NaOH nor with excess NH_(4)OH solution?

Identify the cation in each of the following case Ammonium hydroxide solution when added to the solution B gives white precipitate which dissolves in excess

Identify the salts P 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.

When a KI solution is added to a metal nitrate, a black precipitate is produced which dissolves in an excess of KI to give an organge solution. The metal ion is:
