Interpretation of pKs value 1 (SB-27)

Sulphuric acid is given.Ks(H₂SO₄) be -3, pks(HSO–4) = 1.92.
Which of the following statements is correct? And almost more importantly, why?

1. c(H₂SO₄) > c(HSO–4 ) > c(SO2-4 )
2. c(HSO–4) > c(H₂SO₄) > c(SO2-4)
3. c(H₂SO₄) = c(HSO–4) > c(SO2-4)
4. c(HSO–4) > c(SO2-4) > c(H₂SO₄)
5. c(SO2-4) > c(HSO–4) > c(H₂SO₄)

  Lösung:

  The pKs value for H₂SO₄ is equal to -3This means specifically that Almost all H₂SO₄ to themselves HSO–4 and H⁺ and decomposition.
  The pKs value of 1.92 (i.e. about. 2) for HSO–4 states that at the start of (e.g.) 1000 HSO–4 In the GW about one-hundredth (pKs = 2 = -log0.01) = -log1/100) on the website of the Products (this means SO2-4) The main part is spent on education. HSO–4).
  This gives us the following picture:
  c(HSO–4) > c(SO2-4) > c(H₂SO₄)
