Solving Numerical for Chemistry: Formula of Nitride of a Metal Y

Understanding the Problem

The problem requires us to find the formula of the nitride of a metal Y, and then state the formula of its sulphate and hydroxide. To solve this, we need to understand the basic concepts of chemistry, particularly the nomenclature of compounds.

Formula of Nitride of a Metal Y

The formula of a nitride of a metal Y is given as YN. This means that the metal Y has combined with nitrogen (N) to form a compound.

Understanding the Nitride Formula

In general, the formula of a nitride of a metal is written as M3N (where M is the metal). However, in this case, the formula is given as YN, which suggests that the metal Y has a different valency than the typical metals that form M3N.

Valency of Metal Y

To determine the valency of metal Y, we need to look at the periodic table and find the group number of the metal. The group number of a metal determines its valency. For example, metals in group 1 have a valency of 1, while metals in group 2 have a valency of 2.

Determining the Valency of Metal Y

Since the formula of the nitride is YN, we can infer that the metal Y has a valency of 3. This is because the nitrogen atom has a valency of 3, and the metal Y has combined with it to form a compound.

Formula of Sulphate of Metal Y

The formula of the sulphate of a metal is typically written as MSO4 (where M is the metal). However, in this case, we need to find the formula of the sulphate of metal Y.

Understanding the Sulphate Formula

The sulphate ion (SO42-) has a charge of -2. To balance this charge, the metal Y must have a charge of +2. Since the metal Y has a valency of 3, we can write the formula of the sulphate as Y2(SO4)3.

Formula of Hydroxide of Metal Y

The formula of the hydroxide of a metal is typically written as MOH (where M is the metal). However, in this case, we need to find the formula of the hydroxide of metal Y.

Understanding the Hydroxide Formula

The hydroxide ion (OH-) has a charge of -1. To balance this charge, the metal Y must have a charge of +1. Since the metal Y has a valency of 3, we can write the formula of the hydroxide as Y(OH)3.

Conclusion

In conclusion, the formula of the nitride of a metal Y is YN. The valency of metal Y is 3, and the formula of its sulphate is Y2(SO4)3. The formula of its hydroxide is Y(OH)3.

Key Takeaways

The valency of a metal determines the formula of its compounds.
The sulphate ion has a charge of -2, and the metal Y must have a charge of +2 to balance this charge.
The hydroxide ion has a charge of -1, and the metal Y must have a charge of +1 to balance this charge.
