What would be the effect of adding 15 ml of 15 m sulphuric acid rather than 15 ml of 6M sulphuric acid in the conversion of CuO to CuSO4? How would this change the experimental procedure for the conversion of CuSO4 to metallic copper
Compute the concentrations of all species in a 0.900 M sodium sulfite solution. If it is given that the ionization constants for H2SO3 are Ka1=1.4x10^-2 and Ka2=6.3x10^-8.
Are there any other particular ones more important or can some of them actually have a harmful effect on the human body.
