Chapter 17, Problem 82E

Interpretation Introduction

Interpretation:

The information regarding addition of sodium hydroxide to aluminum compartment that is present along with nickel metal electrode in other compartment is given. The value of $K_{\text{sp}}$ for $\text{Al}{\left(\text{OH}\right)}_3$ is to be calculated.

Concept introduction:

Solubility product is applied only for those ionic compounds that are sparingly soluble. The product of solubility of ions is called solubility product and solubility is present in moles per liter.

The value of $E_{\text{cell}}$ is calculated using Nernst formula,

$E=E°-\left(\frac{RT}{nF}\right)\ln \left(Q\right)$

At room temperature the above equation is specifies as,

$E=E°-\left(\frac{0.0591}{n}\right)\log \left(Q\right)$

To determine: The value of $K_{\text{sp}}$ for $\text{Al}{\left(\text{OH}\right)}_3$.
