A 0.600 g sample of potassium carbonate, K₂CO3 (138.2055 g/mol) is dissolved in 20.00 mL of 0.1700 M hydrochloric acid, HCI. The resulting solution was then titrated with 0.1048 M sodium hydroxide, NaOH and required 24.16 mL to reach end point. Calculate the percentage (w/w) of potassium carbonate in the sample. K₂CO3(aq) + 2HCl(aq) NaOH(aq) + HCl(aq) 2KCl(aq) + H₂O(1) + CO2(g) NaCl(aq) + H₂O(1)
