The hydrogen ion concentration of a 10−-−8 M, HCl aqueous solution at 298 K (Kw = 10−-−14) is
  1. A
    1.0 ×\times× 10−-−8 M
  2. B
    1.0 ×\times× 10−-−6 M
  3. C

Correct answer: C

In HCl solution [H+] = 10-8 M

Also from water, [H+] = 10-7 M

∴\therefore∴ Total [H+] = 10-8 M + 10-7 M

= 1.1 ×10–7 M

≃\simeq≃ 1.0525 ×\times× 10−-−7 M
