Oxalic acid (H2C2O4) is an acid widely used in chemical analysis, industry and veterinary applications. THE Neutralization volumetry is one of the options for determining this acid in raw materials for the industry. Considering this determination, answer the items below. Being that 0.2255 g of a sample of oxalic acid raw material was weighed and titrated completely with 23.2 mL of a 0.1522 mol/L NaOH solution, what is the percent purity of this product? (Pasta molecular oxalic acid 90.03 g mol/L) [Answer; purity = 70.5%] H2C2O4 (aq) + NaOH (aq) → Na2C2O4 (aq) + H2O(l) And suggest an appropriate indicator for the titration of this acid by looking at the titration curve profile below (photo)
