Question

A chemistry student weighs out 0.113g of formic acid HCHO2 into a 250.mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.0800M NaOH solution. Calculate the volume of NaOH solution the student will need to add to reach the equivalence point. Be sure your answer has the correct number of significant digits.

Step 1

113 g. To do this, we first need to find the molar mass of formic acid (HCHO2): - Hydrogen (H): 1.01 g/mol × 2 = 2.02 g/mol - Carbon (C): 12.01 g/mol × 1 = 12.01 g/mol - Oxygen (O): 16.00 g/mol × 2 = 32.00 g/mol Molar mass of HCHO2 = 2.02 g/mol + 12.01 g/mol + Show more…
