Question

Please help

Using the formula pH= -log[H+], a sample of vinegar has a hydronium concentration of 1.6 × 10-3 M. What is the pH of the vinegar? (C.10H)

Question 9 options:

2.8


1.6


10.3


4.1

Answer 1

A

Step-by-step explanation:

To find the pH of vinegar, we can use the given formula pH= -log[H+], where [H+] is the hydronium ion concentration in the vinegar.Substituting the given value of hydronium ion concentration [H+] = 1.6 × 10^-3 M in the above formula, we get:pH = -log(1.6 × 10^-3)Using a calculator, we can evaluate the logarithm to be 2.8.Therefore, the pH of the vinegar is 2.8.Hence, the correct answer is option A) 2.8.
