Litmus has coloured in the solution. When `BaCI_2` solution was added to his. Solution, a white precipitate insoluble in HCI is produced: Write the chemical name and chemical formula of the white precipitate produced when it was added with `BaCI_2`.

When Zn is added to 'CuSO_4' solution, copper is precipitated because of :

When 1 ml Barium Chloride solution is added to the solution given below: Does the white precipitate dis-solve when dilute hydrochloric acid is added to it?

When H_(2)S gas is passed in metal sulphate solution in the presence of NH_(4)OH , a white precipitate is produces the metal is

When lead acetate solution is added to the fusion extract of thiamine, acidified with acetic acid, the colour of the precipitate obtained is

When 1 ml Barium Chloride solution is added to the solution given below: Which substance is the white pre-cipitate?

A salt (A) when heated with K_2 Cr_2 O_7 and conc. H_2 SO_4 liberates a gas which is absorbed in NaOH solution. The NaOll solution turns yellow. When this solution is acidified with acetic acid and lead acetate solution is added, a yellow precipitate (B) is formed. (A) is mixed with MnO_2 and heated with conc. H_2 SO_4 when a gas (C) is evolved which tums starch-iodide paper blue. The compound formed, which turns NaOH solution yellow, is:
