How to calculate PH 2.13 = 0.007M Why?
Please show for me. I want you step by step for me.
Follow the steps from my previous post. Either method gives 0.00741 = (H^+)
To calculate the pH of a solution, you need to use the formula:
pH = -log[H+]
Where [H+] is the hydrogen ion concentration in moles per liter (M). In this case, the given hydrogen ion concentration is 0.007 M.
Step-by-step calculation:
1. Take the negative logarithm (base 10) of 0.007 M:
pH = -log(0.007)
2. Calculate the logarithm using a scientific calculator or logarithm table. In this case:
pH ≈ -(-2.15) (Note: log(0.007) is approximately -2.15)
3. Simplify the double negative sign:
pH ≈ 2.15
Therefore, the pH of a solution with a hydrogen ion concentration of 0.007 M is approximately 2.15.
