Answer:
The answer is endothermic
Answer:
11.83.
Explanation:
<em>∵ pOH = - log[OH⁻]</em>
∵ [OH⁻] = √(Kb.C),
Kb = 1.8 x 10⁻⁵, C = 2.5 M.
∴ [OH⁻] = √(Kb.C) = √(1.8 x 10⁻⁵)(2.5 M) = 6.71 x 10⁻³ M.
∴ pOH = - log[OH⁻] = - log(6.71 x 10⁻³ M) = 2.17.
∵ pH + pOH = 14.
<em>∴ pH = 14 - pOH =</em> 14 - 2.17 = <em>11.83.</em>
