What is the pH of a solution if the [H3O+] is 6.7*10-4m?

1 answer:

8 0

You need 5 basic conversions (some give you a 6th, but all you need are these 5):

1) pH = –log [H+] (negative log of the concentration of the hydronium ion) thus, 
2) [H+] = 10 ^ -pH. 
3) pOH = –log [OH-] and thus, 
4) [OH-] = 10 ^ -pOH 
5) pH + pOH = 14

Answer:

Age ≅ 7500 years

Explanation:

All radioactive decay is 1st order kinetics and described by the expression

A = A₀e^-kt => t = ln(A/A₀) / -k

k = 0.693 / t(half life) = (0.693 / 5730)yrs⁻¹ = 1.21 x 10⁻⁴ yrs⁻¹

t = Age = [ln(0.103/0.255) / - 1.21 x 10⁻⁴] yrs = 7500 years
