We’re being asked to calculate the initital and final pH of the 260.0 mL of pure water after adding 0.0200 mol NaOH.
Let’s first determine what type of base is NaOH:
• Any Group 1A metal when combined with OH-, H-, O2- or NH2- makes a strong base
• Na (Group 1A metal) is paired with OH-
• NaOH → strong base
• Initial pH of the 260.00 mL of pure water
For each of the following solutions, calculate the initial pH and the final pH after adding 0.0200 mol of NaOH.
For 260.0 mL of pure water, calculate the initial pH and the final pH after adding 0.0200 mol of NaOH.
