Problem- What are the concentrations of H+ ? and CO32- ?, respectively, for a 0.073 M carbonic acid solution? Assume there is no loss of any carbonate species via generation of CO2.
I need proficient help to explain each and every step in detail of the above problems.
Based on this information how can I use the experimental standard cell potential, experimental nonstandard cell potential, and 0.10 M of zinc to determine the concentration of copper in the solution
A dry-cleaning solvent (molecular weight = 146.99 g/mol) that contains C, H, and Cl is suspected to be a cancer-causing agent. When a 0.124 g sample was studied by combustion analysis, 0.223 g of CO2 and 0.0301 g of H2O formed.
