1. If it takes 25.0 mL of 0.5 M NaOH solution to completely neutralize 20.0 mL of Oxalic acid solution, what is the concentration of Oxalic acid solution?

2. 28.5 mL of a 0.75 M solution of Oxalic acid is used to neutralize 35.5 mL of sodium hydroxide solution. What is the concentration of the sodium hydroxide solution?

3. Calculate pH of a solution when 12 mL of 0.1 molL-1 Oxalic acid reacts with 5.0 mL of 0.15 molL-1 NaOH.

4. A 20.0 mL sample of Oxalic acid was titrated with 0.15 M NaOH standard solution. It took

23.5 mL of NaOH from the burette to reach the titration end-point.

(a) Write the balance chemical equation for this reaction.

(b) Based on the coefficients of the equation that you have just written, how many moles of NaOH would be consumed by one mole of Oxalic acid?

(c) How many moles of NaOH are contained in the 23.5 mL of 0.15 M NaOH that is delivered from the burette?

(d) How many moles of Oxalic acid must be present to react completely with the NaOH delivered from the burette?

(e) What is the Molarity (M) of the Oxalic acid solution titrated?
