Calculate the pH of the solutions: [H^+]= 1.6 x 10^-3 M
1 answer:
Answer:
A) pH = 2.8
B) pH = 5.5
C) pH = 8.9
D) pH = 13.72
Explanation:
a) [H⁺] = 1.6 × 10⁻³ M
pH = -log [H⁺]
pH = -log [1.6 × 10⁻³ ]
pH = 2.8
b) [H⁺] = 3 × 10⁻⁶
pH = -log [H⁺]
pH = -log [3 × 10⁻⁶ ]
pH = 5.5
c) [OH⁻] = 8.2 × 10⁻⁶
pOH = -log[OH]
pOH = -log[8.2 × 10⁻⁶]
pOH = 5.1
pH + pOH = 14
pH = 14 - pOH
pH = 14 - 5.1
pH = 8.9
d) [OH⁻] = 0.53 M
pOH = -log[OH]
pOH = -log[0.53]
pOH = 0.28
pH + pOH = 14
pH = 14 - pOH
pH = 14 - 0.28
pH = 13.72
