A. When concentrated sulfuric acid is added to water, dissociation takes place in two stages.
stage 1
H2SO4 = H+ + HSO4-
stage 2
HSO4 = H+ + SO42- Ka2 = 1.0 * 10-2
Ka2 is the acid dissociation constant Ka2
(i) Write the expression for the acid dissociation constant Ka2.
(ii) H2SO4 is considered a strong acid whereas HSO4 is considered a week acid

Suggest how the magnitude of the acid dissociation constant for stage 1
compares to Ka2.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
