Question

Для комплексного соединения k2 [pb(oh)6] определить комплексообразователь,его степень окисления и координационное число, записать первичную диссоциацию

Answer 1

K2[Pb(OH)6] - гексагидроксоплюмбат калия
Pb - комплексообразователь
+4- степень окисления Pb
6 - координационное число
K2[Pb(OH)6] = 2K⁺ + [Pb(OH)6]⁻²

Answer 2

Complex Compound K2[Pb(OH)6]

For the complex compound K2[Pb(OH)6], we need to determine the complexing agent, its oxidation state, and the coordination number.

Complexing Agent: The complexing agent for the compound K2[Pb(OH)6] is the hydroxide ion (OH-). It acts as a ligand that forms coordinate covalent bonds with the central metal ion, lead (Pb).

Oxidation State: The oxidation state of the central metal ion, lead (Pb), in the complex compound K2[Pb(OH)6] needs to be determined. The oxidation state of lead can be calculated using the known oxidation states of the other elements in the compound and the overall charge of the complex.

Coordination Number: The coordination number of the central metal ion in the complex compound K2[Pb(OH)6] is the number of coordinate covalent bonds formed with the ligands. It can be determined by counting the number of bonds formed with the ligands.

Primary Dissociation

The primary dissociation of the complex compound K2[Pb(OH)6] can be represented as the separation of the complex into its constituent ions in solution. The dissociation can be expressed using the following equation:

K2[Pb(OH)6] ⇌ 2K+ + [Pb(OH)6]2-

This equation represents the dissociation of K2[Pb(OH)6] into two potassium ions (K+) and the complex ion [Pb(OH)6]2-.
