A solution is prepared at 25C that is initially 0.50 M in chlorous acid (HClO2), a weak acid with Ka= 1.1 x 10^-2, and 0.4M in (NaClO2). Calc the pH of the solution. Round 2 decimal places
Homework Answers
Ka = 1.1*10^-2
pKa = - log (Ka)
= - log(1.1*10^-2)
= 1.959
use:
pH = pKa + log {[conjugate base]/[acid]}
= 1.959+ log {0.4/0.5}
= 1.862
Answer: 1.86
