Ph of 10–8 m hcl solution is nearly
Web10 -8 M indicates a very dilute solution. Thus, H + ions of water cannot be ignored. But dissociation of water is suppressed due to common ion effect. ∴ [H +] ≠ 10 -7 M but less than 10 -7 M. α α H A 2 O ↽ − − ⇀ H A + ( 10 A − 8 + α) + OH A − α K w = [H +] [OH –] = (10 –8 + α) α ∴ α 2 + α × 10 -8 - 10 -14 = 0 WebCalculate the pH of 10 −8 M HCl.
