Given that kw for water is 2.4× 10–14 at 37 °c, compute the ph of a neutral aqueous solution at 37 °c, which is the normal human body temperature.

pH = 6.81.

Explanation:

H₂O(l) ⇄ H⁺(aq) + OH⁻(aq),

Kw = [H⁺][OH⁻] = 2.4 x 10⁻¹⁴.  

in pure water and neutral aqueous solution, [H⁺] = [OH⁻]  

So, Kw = [H⁺]²

∴ 2.4 x 10⁻¹⁴ = [H⁺]²

∴ [H⁺] = 1.55 x 10⁻⁷ M.

∵ pH = - log [H⁺]  

pH = - log (1.55  x 10⁻⁷) = 6.81.

is has three carbons, so the answer is propylamine.
