Consider the following observation: ltbRgt `M^(n+) +HCl to ` white precipitate `overset(Delta)to` water soluble.
The metal ion `M^(n+)` will be

Consider the following sequence of tests, M^(n+) to HCl to white precipitate overset(Delta)to water soluble. The metal ion (M^(n+)) would be:

Consider the following sequence of tests, M^(n+) overset(HCl)to white precipitate overset(Delta)to water soluble. The metal ion (M^(n+)) would be:

Consider the following observation: M_(n+) + HCl (dilute) to white precipitate overset(Delta)to water soluble overset(CrO_(4)^(2-) yellow precipitate. The metal ion M^(n+) will be:

The metallic salt (XY) is soluble in water. (a) When the aqueous soluble of (XY) is treated with NaOH solution, a white precipitate (A) is formed. In excess of NaOH solution, a white precipitate (A) is formed. In excess of NaOH solution, white precipitate (A) dissolves to form a compound (B) . When this solution is boiled with soild NH_(4) Cl , a precipitate of compound (C) is formed. (b) An aqueous solution on treatment with BaCl_(2) solution gives a white precipitate (D) white is insoluble in conc HCl . ( c) The metallic salt (XY) forms a double salt (E) with potassium sulphate. Identify (XY),(A),(B),(C),(D) and (E) .

A metal (M) burns with dazzling brilliance in air to give a white powder. The white powder reacts with water to form a white precipitate and a colourless gas with a characteristic smell. The metal (M) decomposes hot water but not cold water, liberating the inflammable hydrogen gas. The metal (M) is:
