Let's calculate the pH of the NaOH solution. Step 1: Determine the concentration of hydroxide ions (OH^-). Sodium hydroxide (NaOH) is a strong base, meaning it dissociates completely in water. Therefore, the concentration of hydroxide ions (OH^-) is equal to the initial concentration of NaOH. [OH^-] = 0.02 \, M Step 2: Calculate the pOH of the solution. The pOH is calculated using the formula: pOH = -_10[OH^-] pOH = -_10(0.02) pOH ≈ 1.70 Step 3: Calculate the pH of the solution. The relationship between pH and pOH at 25°C is: pH + pOH = 14 pH = 14 - pOH pH = 14 - 1.70 pH = 12.30 The pH value of 0.02 M NaOH is 12.30. 3 done, 2 left today. You're making progress.
