Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

1. Would it matter if the syringe you used for your citric acid solution in the titration was wet with distilled water?

2, Why did you need to remove air bubbles from the tip of the syringe?

3. 15.0 mL of 1.600 M NaOH solution exactly neutralizes 20.0 mL of an unknown triprotic acid solution (H₃X). Calculate the molarity of the triprotic acid solution. You must show all work with units to receive credit. Your answer must have the correct units and the correct number of significant figures to receive full credit.

4. Why is it important that the chemical used as the primary standard is non- hygroscopic and pure? Why is it important to dry the primary standard to a constant mass?
