WebWell, first you will need to determine the concentration of the sulphuric acid solution. The molecular weight of sulphuric acid is 98 g/mole so, 0.98 g corresponds to 0.01 moles and in 1 L, this would give a solution that is 0.01. The reaction that will occur when you mix the solution of sodium carbonate with the sulphuric acid is: WebJul 2, 2016 · nHCl = 3.6722 × 10−3. ∴ The no. moles used up: = (6.400 − 3.6722) ×10−3 = 2.7228 × 10−3. From the original equation you can see that the no. moles of Na2CO3 … WebThe complete equation for this reaction, and the one on which you will base your calculations, both for the standardization of HCl and the determination of the mass % Na … guiltfree industries
