At equivalence point:
Solve for molarity of acid (i.e HNO3):
A solution of HNO3 is standardized by reaction with pure sodium carbonate.
2H+ + Na2CO3 → 2Na+ + H2O + CO2
A volume of 25.36 0.06mL of HNO3 solution was required for complete reaction with 0.9572 0.0008 g of Na2CO3 (FM 105.988 0.001). Find the molarity of the HNO3 and its absolute uncertainty.
