When choosing a suitable indicator for a titration between a strong acid and a weak base, the indicator should change color in the ph range of:
exactly 7
less than 7 (slightly acidic)
greater than 7 (slightly basic)
near 14 (very basic)

Calculate the molarity of the solution. 6.02 x 1022 molecules of hci (molecular weight = 36.5 g/mole) in 2.0 liters of water m

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.

The name of the ion, s2-, is: sulfurous ion sulfide ion sulfur ion sulfate ion
