Question
How is pH calculated?
Question 2
Select one:
- a.
log[H3O^+]
- b.
−log−log[OH−]
- c.
−log−log[H3O^+]
- d.
log[OH−]
Solution
To calculate pH, we can break down the problem into the following steps:
1. ### Break Down the Problem
We need to determine which option correctly represents the formula for calculating pH. The pH is a measure of the hydrogen ion concentration in a solution.
2. ### Relevant Concepts
The pH is calculated using the formula: where is the concentration of hydronium ions in moles per liter.
3. ### Analysis and Detail
- Option (a) states: , which is incorrect because the pH formula requires the negative logarithm.
- Option (b) states: , which does not make sense in the context of calculating pH.
- Option (c) states: , which is correct as it directly uses the pH formula.
- Option (d) states: , which is incorrect because it relates to the pOH, not the pH.
4. ### Verify and Summarize
From the analysis, option (c) correctly represents the pH calculation, as it directly applies the formula needed to find pH.
Final Answer
The correct option is c. .
