A shipment of crude sodium carbonate must be assayed for its Na2CO3 con- tent. You receive a small jar containing a sample from the shipment and weigh out 9.709 g into a flask, where it is dissolved in water and diluted to 1.0000 L with distilled water. A 10.00 mL sample is taken from the flask and titrated to the equivalence point with 16.90 mL of a 0.1022 M HCl solution. Determine the percentage of Na2CO3 in the sample. Write the titration equation to get the mole ratio.

Question
A shipment of crude sodium carbonate must be assayed for its N22CO3 con- tent.
You receive a small jar containing a sample from the shipment and weigh out 9.709
g into a flask, where it is dissolved in water and diluted to 1.0000 L with distilled
water. A 10.00 mL sample is taken from the flask and titrated to the equivalence
point with 16.90 mL of a 0.1022 M HCI solution. Determine the percentage of
Na2CO3 in the sample. Write the titration equation to get the mole ratio.
