A standard nitric acid solution is prepared using 0.425 g of sodium carbonate, Na2CO3. Find the molarity of the acid if 33.25 mL are required to reach a permanent endpoint. 2 HNO3 + Na2CO3 = 2 NaNO3 + H2O + CO2
Homework Answers
Ans :
Number of mol of Na2CO3 = mass / molar mass
= 0.425 g / 105.99 g/mol = 0.004 mol
So number of mol of nitric acid = 2 x 0.004 mol = 0.008 mol
Molarity of acid = mol HNO3 / volume (L)
putting values :
= 0.008 mol / 0.03325 L
= 0.241 M
Add Answer to:
A standard nitric acid solution is prepared using 0.425 g of
sodium carbonate, Na2CO3. Find the...
