Answer 1

1.0 × 10⁻⁸ mol/L

Step-by-step explanation:

Calculating pH & pOH

We're given:

• [OH-] = 1.0 × 10⁻⁶ mol/L
• [H+] = ?

Determine pOH:

pOH = -log[OH-]

pOH = -log[1.0 × 10⁻⁶ mol/L]

pOH = 6

Determine pH:

pH = 14 - pOH

pH = 14 - 6

pH = 8

Determine [H+]:

pH = -log[H+]

8 = -log[H+]

[H+] = 10⁻⁸ mol/L
