Question

The hydrogen ion​ concentration, ​[h ​], in a certain cleaning compound is [h ] =2.4 x 10⁻¹² . use the formula phlog​ [h​] to find the ph of the cleaning compound.

Answer 1

The pH of the cleaning compound with a hydrogen ion concentration of [H+] = 2.4 x 10⁻¹² is calculated using the formula pH = -log[H+]. By taking the negative log of the hydrogen ion concentration, you arrive at the pH which indicates the acidity or alkalinity of the solution.

Step-by-step explanation:

To calculate the pH of a cleaning compound with a hydrogen ion concentration of [H+] = 2.4 x 10⁻¹², you use the formula pH = -log[H+].

For the given compound:

1. Insert the given concentration into the formula: pH = -log(2.4 x 10⁻¹²).
   
2. Use a calculator to find the negative log of the hydrogen ion concentration. Press the log button, enter 2.4 x 10⁻¹², and then take the negative of this value.
   
3. The result is the pH of the cleaning compound. For example, if we assume the negative log of 2.4 x 10⁻¹² is approximately 11.62, then pH = 11.62.
   

The pH scale is a logarithmic measure that defines the acidity or alkalinity of a solution, with a pH of 7 being neutral.
