Question

1. white distilled vinegar has a hydrogen ion h⁺ concentration of approximately 0.003162277. what is the ph level of white distilled vinegar? use the formula ph = -logh⁺.

○ ph = 2.0
○ ph = 2.5
○ ph = 3.5
○ ph = 3.0

Explanation:

Step1: Recall pH formula

$\text{pH} = -\log[\text{H}^+]$

Step2: Substitute given $[\text{H}^+]$

$\text{pH} = -\log(0.003162277)$

Step3: Calculate the logarithm

$\log(0.003162277) \approx -2.5$

Step4: Compute final pH

$\text{pH} = -(-2.5) = 2.5$

Answer:

C. pH = 2.5
