Q72P - Chemistry: Molecular Nature Of Matter And Change

Question

A concentration cell consists of two H2/H half-cells. Half cell A has H2 $\mathbf{0}\mathbf{.}\mathbf{95}$ atm bubbling into $\mathbf{0}\mathbf{.}\mathbf{10}$ M HCl. Half-cell B has H2 at $\mathbf{0}\mathbf{.}\mathbf{60}$atm bubbling into $\mathbf{2}\mathbf{.}\mathbf{0}$M HCl. Which half-cell houses the anode? What is the voltage of the cell?

Step-by-Step Solution

Answer

Anode: Half cell A

_{$E_{cell}=0.0385V$}

Step 1: Understand the question

The question asks: A concentration cell consists of two H2/H half-cells. Half cell A has H2 0 . 95 atm bubbling into 0 . 10 M HCl. Half-cell B has H2 at 0 . 60 atm bubbling into 2 . 0 M HCl. Which half-cell houses the anode? What is the voltage of the cell?

Step 2: Apply Chemistry knowledge

Using fundamental Chemistry concepts to analyze the problem.

Step 3: Formulate the answer

Anode: Half cell A E c e l l = 0 . 0385 V

Step 4: Conclude

The answer is: Anode: Half cell A E c e l l = 0 . 0385 V
