What is the pH of beer in which the hydrogen ion concentration is 5.6 × 10−7 M?
The question is –
What is the pH of beer in which the hydrogen ion concentration is 5.6 × 10−7 M?
Answer:
⇒ The pH of the beer is approximately 6.25.
Explanation:
The pH of a solution is a measure of the hydrogen ion concentration, and it can be calculated using the formula:
⇒ pH = -log[H+]
where [H+] is the hydrogen ion concentration. Let’s apply this to your example:
Step 1: Identify the Hydrogen Ion Concentration
⇒ Hydrogen ion concentration [H+] = 5.6 x 10-7 M
Step 2: Apply the pH Formula.
We need to take the negative logarithm (base 10) of this number. Remember, the base of the logarithm is usually 10 when dealing with pH.
⇒ pH = -log(5.6 x 10-7)
Step 3: Calculate the pH
This will require a calculator that can compute logarithms. If we use a calculator, we get:
∴ pH = -log(5.6 x 10-7) = 6.25
So, the pH of the beer is approximately 6.25.
