Solubility in Ammonia (Group 1)

Q.

A metal which is unaffected by dilute or concentrated acid.

Q.

Solution of sodium metal in liquid ammonia is strongly reducing due to the presence of the following in solution

1. Sodium hydride

2. Solvated electrons

3. Sodium amide

4. Sodium atoms

Q.

Read the following and select one the correct answer:

Statement I: Alkali metals dissolve in liquid ammonia to give a blue solution

Statement II: Alkali metals dissolve in liquid ammonia to give solvated species of the type $\left[Na\right(N{H}_3{)}_n{]}^{+}$

1. Statement I and Statement II are both correct. Statement II correctly explains Statement I

2. Statement II is correct and Statement I is wrong

3. Statement I and Statement II are both correct. Statement II does not explain Statement I

4. Statement I is correct and Statement II is wrong

Q. Highly pure dilute solution of sodium in liquid ammonia
(IIT-JEE, 1998)

1. Shows blue colour
2. Exhibits electrical conductivity
3. Produces sodium amide
4. Produces hydrogen gas

Q. Which of the following arrangements does not represent the correct order of the property stated against it?

1. $N{i}^{2+}<C{o}^{2+}<F{e}^{2+}<M{n}^{2+}$ : Ionic size
2. $C{o}^{3+}<F{e}^{3+}<C{r}^{3+}<S{c}^{3+}$ : stability in aqueous solution
3. $V^{2+}<C{r}^{2+}<M{n}^2<F{e}^{2+}$ : paramagnetic behavior
4. $Sc<Ti<Cr<Mn$ : Number of oxidation states

Q. Statement I: Alkali metals dissolve in liquid ammonia to give blue solutions.
Statement II: Alkali metals in liquid ammonia give solvated species of the type $\left[M\right(N{H}_3{)}_n{]}^{\oplus }$ (M = alkali metals).
(IIT-JEE, 2007)

1. Statement I is true; Statement II is false.
2. Statement I is true; Statement II is true; Statement II is not the correct explanation for Statement I.
3. Statement I is true; Statement II is true; Statement II is the correct explanation for Statement I.
4. Statement I is false; Statement II is true.

Q. A metal X forms a water soluble salt XNO3. When an aqueous solution of XNO3is added to common salt solution, then a white precipitate of compound Y is formed along with sodium nitrate solution. Metal X is said to be the best conductor of electricity and it does not evolve hydrogen when put in dilute hydrochloricacid.
(a) What is metal X?
(b)What is salt XNO3?
(c)Name the compound Y?
