Tests for Lead(II) Ion

Formation of which complex, among the following, is not a confirmatory test of ${\mathrm{Pb}}^{2+}$ ions

Which one doesn't gives ${\mathrm{Pb}}^{+2}$ test?

The reaction of $\mathrm{Pb}{\left({\mathrm{NO}}_3\right)}_2$ and $\mathrm{NaCl}$ in water produces a precipitate that dissolves upon the addition of $\mathrm{HCl}$ of appropriate concentration. The dissolution of the precipitate is due to the formation of

Write the chemical reaction of the product formed by reaction of ${\mathrm{Pb}}^{2+}$ with hydrogen sulphide in acidic medium.

_____ and _____ ions give white precipitates with $\text{NaOH}$ solution which are soluble in excess of the reagent. 

Name the probable cation present in the following observation:

White precipitate insoluble in ${\mathrm{NH}}_4\mathrm{OH}$ but soluble in $\mathrm{NaOH}$.

Addition of $\mathrm{KI}$ to $\mathrm{Pb}$ salt gives a precipitate. The colour of precipitate is

Which of the following is incorrectly matched ?

Read the following sequence of reactions:

What are the compounds $\mathrm{D}$ and $\mathrm{E}$?

The compound which will turn black colour on adding ${\mathrm{NH}}_4\mathrm{OH}$ to it is

Which of the following metal ions does not form a complex with ammonia?

What are the cations present in the salt ?

Consider a colorless salt (X) which is soluble in water and also in alcohol and amines. Iron (II) sulphate can easily reduce a solution of (X). (X) gives a brown gas (Y) and a grey residue on strong heating . (X) dissolves in ammonia to give a solution (Z) which gives silver mirror with aldehydes. A solution of (X) also reacts with potassium chromate solution to gives a brick red precipitate. Choose the correct option :

Choose the correct option in which the compound gives a precipitate with $\mathrm{Pb}{\left({\mathrm{NO}}_3\right)}_2$ but not with $\mathrm{Ba}{\left({\mathrm{NO}}_3\right)}_2$.

Among these compounds, the ones that are either sparingly soluble or insoluble in ${\mathrm{NH}}_4\mathrm{OH}$ solution are:

$\begin{array}{ccccc}\text{I. Ni}{\left(\text{OH}\right)}_2& {\text{II. Ag}}_2{\text{CrO}}_4& \text{III. Fe}{\left(\text{OH}\right)}_3& \text{IV. Al}{\left(\text{OH}\right)}_3& {\text{V. Ag}}_2{\text{CO}}_3\end{array}$
