Answer:
3.47 x 10⁻⁹.
Explanation:
- The concentration of OH⁻ = 0.16 M.
∵ [OH⁻] = √(Kb)(C).
Kb for ammonia = 1.8 x 10⁻⁵.
∴ [OH⁻] = √(Kb)(C) = √(1.8 x 10⁻⁵)(0.16 M) = 2.88 x 10⁻⁶ M.
<em>∵ [H⁺][OH⁻] = 10⁻¹⁴.</em>
∴ [H⁺] = 10⁻¹⁴/[OH⁻] = 10⁻¹⁴/(2.88 x 10⁻⁶) = 3.47 x 10⁻⁹ M.
<em>∵ pH = - log[H⁺]</em> = - log(3.47 x 10⁻⁹) = <em>8.459 ≅ 8.46.</em>
Answer:
Water is much smaller than either of the previous substances and exhibits weaker dispersion forces, but its extensive hydrogen bonding provides stronger intermolecular attractions, fewer molecules escaping the liquid, and lower vapor pressure than for either diethyl ether or ethanol.
