Analysis of Basic Copper Carbonates
The %w/w Cu in a synthetic basic copper carbonate may be found by reducing and isolating the copper as Cu metal. To calculate the %w/w Cu we use the following formula The […]

Calculating HCl Molarity and Titration Error
In determining the concentration of HCl by titrating against the primary weak base TRIS, the molarity of HCL is calculated using the following equation where GFW is the gram formula weight of […]
Uncertainity in Dispensing a Reagent
Concentrated HCl is 37.2% w/w HCl (±0.5% w/w) and has a density of 1.19 g/mL (±0.01 g/mL). Suppose that you need to dispense 0.0500 mol of HCl with an uncertainty of no […]
Propagation of Error in Preparing Solutions
Suppose you have a bottle of 53.4% w/w NaOH (the density of which is 1.52 g/mL) from which you are to prepare a 1.000-L solution of 0.534 M NaOH. Two obvious ways to […]
