# Volumetric Analysis

### Revision

What does a volumetric flask need to be washed with prior to starting a titration experiment? Washed with deionised water
What does a conical flask need to be washed with prior to starting a titration experiment? Washed with deionised water
What does a burette need to be washed with prior to starting a titration experiment? Washed with deionised water & acid or base
What does a pipette need to be washed with prior to starting a titration experiment? Washed with deionised water & acid or base
What is the end point of a titration? The point where an indicator changes colour
What is the equivalence point of a titration? The point where the reaction is complete. The acid and base have reacted in a mole to mole ratio. There are equivalent amounts of acid and base
0.800 g of anhydrous sodium carbonate, Na2CO3(s), is transferred to a 150.0 mL volumetric flask and made up to the mark with distilled water. What is the concentration of the aqueous sodium carbonate solution in mol/L in the flask? 0.0503 mol/L
What mass of potassium hydrogen phthalate, KH(C8H4O4), in grams, must be weighed out in order to make 200.0 mL of 0.250 mol/L KH(C8H4O4)(aq) ? 10.2 g
In a titration of sulfuric acid against sodium hydroxide, 32.20mL of 0.250M NaOH is required to neutralize 26.60mL of H2SO4 . Calculate the molarity of the sulfuric acid. H2SO4(aq)+2NaOH(aq)→Na2SO4(aq)+2H2O(l) 0.151 M
Calculate the concentration of a 25 mL NaOH solution if 35 mL of 1.25 M HCl is needed to titrate to the equivalence point. NaOH + HCl → NaCl + H2O 1.75 M
