Hitunglah ph larutan berikut. B. Ca(oh)2 0,005m C. Hno3 0,005m Plis langsung dikumpulin soal nya!!

Ca(OH)2 ⇒ Ca⁺² + 2OH⁻
valensi basa : 2
[OH⁻] : 2 . 5 x 10⁻³
= 10 x 10⁻³ = 10⁻²
pOH = -log 10⁻²
= 2
pH = 14-2 =12

HNO₃⇒H⁺ + NO₃⁻
valensi asam : 1
[H⁺] = 1 . 5 x 10⁻³
=5 x 10⁻³
pH = -log 5 x 10⁻³
-log 5 + 3
= - 0,69 + 3
pH = 2,31
