Answer:

(14)The pH is 8.3 and is basic

(15) pOH = 11.0 The solution is acidic

Step-by-step explanation:

(14) From the question,

pH = -log[H₃O⁺]............... Equation 1

Given: H₃O⁺ = 5.6×10⁻⁹ M

Substitute the value above into equation 1

pH = -log[5.6×10⁻⁹]

pH = 8.3

The pH is 8.25 and is basic.

(15)

pOH = -log[OH⁺]................ Equation 2

Given: [OH⁺] = 8.34×10⁻¹² M

Substitute into equation 2

pOH = -log[8.34×10⁻¹²]

pOH = 11.0 Hence the solution is acidic
