WebbBVP Medical 2013: The pH of a 1.0× 10-8M solution of HCl is (A) 6 (B) 7 (C) 8 (D) 6.98 . Check Answer and Solution for above Chemistry question - Tardigrade Webb3 mars 2024 · The exact solution is then. x = − 10−8 2(1) ± √(10−8)2 − 4(1)( − 10−14) 2(1) = − 5 ×10−9 ± √4.01× 10−16 2. = − 5 ×10−9 ± 1.001 × 10−7. The only physical answer is 9.51 ×10−8M. This now gives: [H+] = 9.51 × 10−8M. [OH−] = 1.05 ×10−7M. You can convince yourself that Kw still holds.

WebbFor example, at a pH of zero the hydronium ion concentration is one molar, while at pH 14 the hydroxide ion concentration is one molar. Typically the concentrations of H + in … WebbThus, with pH = -log concentration of H+, the 1 M solution of HCl will give the pH of -log 1 or 0 (Zero), because 10 ^0 = 1. The pH of 1 M hydrochloric acid is zero. The reason is that pH is defined as negative 1 times the log base 10 of [H+], or the proton concentration in moles per liter. Suggest Corrections. 20.
