What is the function of indicator in a titration? Edit View Insert Format Tools Table 12pt ✓ Paragraph BIU IU AT²V 2 T² : C

A titration of 40.0 mL of a sulfuric acid (H₂SO₄) solution of unknown concentration with a standardized 1.55 M Ba(OH)₂ solution requires 23.0 mL to reach the second equivalence point. What is the concentration of the H₂SO₄ solution?

1.00 x 10-² A student was titrating a solution of HC4H7O₂ with a Sr(OH)2 solution. Determine the pH at a particular point in the titration. Do this by constructing a BCA table and determining the pH. Complete Parts 1-2 before submitting your answer. Before (mol) Change (mol) After (mol) NEXT > 40.0 mL of a 0.200 M HC4H7O2 solution was titrated with 100 mL of 0.100 M Sr(OH)2 (a strong base). Fill in the ICE table with the appropriate value for each involved species to determine the moles of reactant and product after the reaction of the acid and base. You can ignore the amount of water in the reaction. 0 -1.00 x 10-² 1 HC4H-O₂(aq) + 0.100 1.20 x 10-² 0.200 OH-(aq) -1.20 x 10-² 2.00 x 10-³ 2 2.00 x 10-² H₂O(l) + -2.00 × 10-³ -2.00 x 10-² C4H7O₂ (aq) 8.00 x 10-³ RESET -8.00 x 10-³
