Question

2. If lime juice has a pH of 1.7, what is the concentration of hydrogen

ions (in mol/L) in lime juice, to the nearest hundredth? Use the
formula pH = -log[H +].

Answer 1

Answer:0.02 mol/L

Explanation:

Given: pH = 1.7

Required: [H+]

Equation: pH = -log [H+]

Solution:

Take the antilog of both sides

[H+] = antilog(-pH)

Antilog(-pH) is equal to 10^-pH. Therefore

[H+] = 10^-pH

Solve for [H+]

[H+] = 10^-1.7

Answer: [H+] = 0.02 mol/L
