pH of solution

Chemistry Level 1

Consider that:

  • In a closed system, only 10% of the \(\ce{CO2}\) dissolves into the water.
  • Before was 1 mol of \(\ce{CO2}\) and 1 liter of \(\ce{H2O} \).
  • Considering the complete ionization as a function of H + and \(\ce{H2CO3}\), and its two steps.
  • The ionization constant is \(5.0 \times 10^{-7} \text{ mol / L} \).
