Give examples and explain with equations: (a)Two colourless solution give a black precipitate on mixing. (b)Two colourless solutions give a red precipitate on mixing, soluble in excess of one of them. ( c)Two colourless solutions give a white precipitate on mixing, soluble in ammonium hydroxide. (d)Two colourless solutions give a yellow precipitate on mixing.

Which one of the following gives white precipitate with AgNO_(3) ?

Identify the cation (positive ion) and anion (negative ion) in - 'A','B' & 'C'. Also identify P, Q, R, S, T, U, V, W. a] Substance 'A' is water soluble and gives a curdy white precipitate 'P' with silver nitrate solution. 'P' is soluble in ammonium hydroxide but insoluble in dil. HNO_3 . Substance 'A' reacts with ammonium hydroxide solution to give a white precipitate ' soluble in excess of NH_4OH . b] A solution of substance 'B' is added to barium chloride solution. A white ppt. 'R' is formed, insoluble in dil. HCl or HNO_3 . A dirty green ppt. 'S' is formed on addition of ammonium hydroxide to a solution of 'B' and the precipitate is insoluble in excess of ammonium hydroxide. c] Substance 'C' is a coloured, crystalline salt which on heating decomposes leaving a black residue 'T'. On addition of copper turnings and conc. H_2SO_4 to 'C' a coloured acidic gas 'U' is evolved on heating. A solution of'C' is added to NaOH soln. until in excess. A pale blue ppt. 'P' is obtained insoluble in excess of NaOH A solution of 'C' is then added to NH_4OH soln. in excess to give an inky blue solution 'V'. A solution of 'C' is warmed and hydrogen sulphide gas is passed through it. A black ppt. 'W' appears.

[i.e. white ppt. insoluble in dil. HCI] ii) Which two solutions will give a white ppt. when treated with dil. HNO_3 & AgNO_3 soln. iii) Which soln. will give a white ppt. when either dil. HCl or dil. H_2SO_4 , is added to it. iv) Which soln. becomes a deep/inky blue colour when excess of ammonium hydroxide is added to it. v) Which solution gives a white precipitate with excess ammonium hydroxide solution.

Identify the acid which matches the following description The acid on mixing with lead nitrate solution produces a white precipitate which is insoluble even on heating
